Formula Drift Round 1: The Streets of Long Beach

April 1, 2017

By Richard Fong

IMG_4074_edited

On the streets of Long Beach, April 1st was no Fool’s Day. Drivers waged fierce battles in the first round of the Formula Drift Championship, leaving no room for anyone faint of heart or too timid to push beyond the limit.

 

Now in its fourteenth year, Formula Drift kicked off the 2017 season on a moderate spring day in Long Beach. The weather could not have been more conducive for a day of tire-smoking fun and enjoyment for all. Attendees could walk through the competitor pits while also checking out the expanded vendor row that occupied the area adjacent to the pits as well as the infield behind the bleachers with the AutoCon Car Show.

IMG_4255_edited

Bye, Bye, Bye

As fans of drifting, we were bummed about the number of bye runs that kicked off the Top 32 eliminations. The top five drivers enjoyed automatic advances into the sweet 16 round for a couple of reasons. First, the usual attrition that comes with drifting, K-rails and tire barriers and, second, a reduction in the number of qualified drivers on the Pro roster. There just weren’t enough to fill a field of 32. We are hopeful that more drivers will see the opportunity to compete and fill the driver list in the near future.

IMG_3133_edited

Upsets Abound

Despite the number of bye runs, the 2017 season kicked off with a shake-up of the norm as numerous upsets throughout the eliminations by up-and-coming drivers sidelined veterans and champions alike. Top qualifier Vaughn Gittin Jr. faced elimination in the Top 16 round at the hands of Dean “Karnage” Kearney.

IMG_2925_edited

Former champions Dai Yoshihara and Michael Essa faced off in the first round. Yoshihara suffered an unfortunate mishap when he snapped a power steering belt just before finishing turn 10. This caused him to straighten out and almost collide with the K-rail, suffering a loss.

IMG_4450_edited

The 2015 champion Fredric Aasbo competed in his new Toyota Corolla iM drift car as if he’d been driving it for years. After his first round bye run, he beat Kristaps Bluss to move on to the Great 8 against Alex Heilbrunn. Heilbrunn also enjoyed a first round bye before beating Juha Rintanen to advance to his match up with Aasbo. Heilbrunn upset the Norwegian Hammer and advanced to the Final 4.

IMG_4004_edited

Three-time champion Chris Forsberg defeated Alec Hohnadell in the first round before facing Ken Gushi in a too-close-to-call second match. Forsberg and Gushi delivered a great battle that many felt could have gone for a one-more-time rebattle, but the judges ruled in Forsberg’s favor to the dismay of the crowd, who chanted a chorus of “One-More-Time” as the judges’ decision was posted on the Jumbotron. Forsberg faced elimination by the number two qualifier, James Deane in the Great 8. Deane enjoyed a bye run before defeating Essa on his way to face Forsberg. Deane’s victory over Forsberg put him into the Final 4.

IMG_4617_edited

First Time Finalists

Bakchis has competed for seven years and podiumed six times, while Tuerck has thirteen years in Formula Drift competition and twelve podiums to his credit, according to driftstats.com. By comparison, Heilbrunn has just one year in Formula Drift Pro2 and one year in the Pro Championship. Deane competed at four rounds of Formula Drift competition back in 2010 and returned for the first time since to compete in the USA at Long Beach. Bakchis paired with Heilbrunn while Tuerck matched up with Deane.  The sophomore drivers each prevailed, putting both into the finals for the first time. When the smoke cleared and the contenders lined up in front of the grandstands, the judges awarded James Deane his first Formula Drift event victory as Heilbrunn proudly claimed his first podium as runner up. Since Tuerck qualified higher than Bakchis, he was awarded third spot on the podium.

IMG_4667_edited

With the first round in the books, Formula Drift and its roster of drivers prepare to make the trek across the US of A to Round 2 at Orlando Speed World. On the weekend of April 28-29, the state of Florida will feel the thunder as both the Pro and Pro2 divisions lay down rubber to the tarmac. This season is already shaping up to be an exciting one so be sure to keep your eyes focused on the Formula Drift Championship!

The Los Angeles Convention Center hosts some of the most epic automotive events in the nation. On March 25, 2017, AutoCon filled the halls with a few of the finest machines from across the country. Crowds came in droves, lining up outside the convention hall for hours, waiting for their chance to file into the grand halls of the Convention Center. For an event held on a Sunday afternoon from 1pm-to-8pm, thousands of attendees waited in lines that snaked all the way out the front of the convention hall as interest in the event and the excitement of anticipation built up to a fever pitch.

E16A6391

Once inside, the fans were greeted by a balanced presentation of high quality vehicle builds ranging from vintage rides and domestic muscle to aggressive imports and European exotics. AutoCon attracts a strong following of quality builds, ensuring that everyone in attendance experiences the finest in vehicle construction. There was no shortage of eye candy and inspiration for the car lover in us all.

Slammed chassis, custom paint, aggressive aerodynamics and numerous engine swaps could be found throughout the vast convention halls. Eye catching machines showcased the latest trends and delivered a good idea of what is popular in the scene. The bolt-on overfender styling of Rocket Bunny, Liberty Walk and RAUH-Welt BEGRIFF (RWB) continues its foothold in the scene as platforms ranging from the accessible FR-S/BRZ up to the more exotic GT-Rs and Ferraris featured wide over fenders and aggressively offset wheels.

Honda chose this particular venue, rather than a traditional main-stream auto show like Detroit or Los Angeles to debut its entry in the hot hatch category: the 2017 Civic Type-R. This machine just captured the FWD track record at the N?rburgring Nordschleife Circuit from the previous record holder, the Volkswagen GTI Clubsport, with a lap time of 7 minutes 43.8 seconds. (Check out the video on YouTube)

Brake Systems 401: Bigger Calipers to Clamp Down on Speed

By Richard Fong

stillen_u_banner_v1 - Copy

It’s no secret that brakes serve an important role from the standpoint of both performance as well as safety. After all, the typical street vehicle (cars, motorcycles, etc.) generates approximately 80-percent of stopping power from its front brakes. In Brake Systems 101, we covered some of the basics of braking, focusing on pads and rotors. Brake Systems 201 put emphasis on two-piece rotors as well as stainless-steel braided lines and higher performance brake fluids. The third installment, Brake Systems 301, introduced one component of the Big Brake System, larger rotors, which increases the heat capacity and friction surface area relative to stock. Now we’re going to look at the visual and functional star of the big brake kit, the brake caliper.

3R1A9721 edited - Copy

Applying Pressure

Brake calipers serve one purpose, to squeeze the pads against the rotor to generate friction, shave speed and eventually bring the vehicle to a stop. Calipers come in a variety of types, configurations and sizes. One of the most common factory caliper types is the sliding caliper, where one or more pistons press against the inboard brake pad, while the brake caliper housing slides inward, pulling on the outer pad to equalize the pressure to both sides of the rotor. Automakers often favor this type of caliper for its low cost and satisfactory stopping performance on the street. Unfortunately, these calipers suffer from excessive deflection under performance conditions and contribute to less than ideal braking performance.

IMG_9546IMG_9586

3R1A9741_edited - Copy

Sliding calipers feature unopposed piston(s) (Red Arrow) that apply pressure to the inboard brake pad against the rotor. This causes the floating portion of the caliper (Blue Arrows) to slide on pins (Green Arrows) while pulling the outboard brake pad against the rotor. The Yellow Arrow indicates the brake rotor and the direction that it rotates.

By contrast, fixed or opposed calipers, as the name implies, do not slide or move. There are an equal number of pistons that press on the pads isometrically to ensure equal pressure is applied to both sides for even wear.

3R1A9695_edited

A fixed caliper features symmetrically opposed pistons and a caliper body that does not move. In this example of an AP Racing By STILLEN RadiCAL six-piston caliper, the Black Arrows show the position and direction of movement of the pistons. This isometric positioning ensures isometric pressure applied to the brake pads against the rotor surface.

Bigger Rotors, Bigger Calipers

Increasing the heat capacity and the friction surface area by way of larger rotors prompts the use of correspondingly larger calipers. Upgrading to larger brake calipers and the use of larger brake pads make best use of the increased area availed by larger rotors for improved stopping performance. Larger calipers also tend to employ multiple pistons to ensure even application of pressure to the backing plate of the larger pads as they generate friction with the rotor surface.

3R1A9683_edited   3R1A9702_edited

Pumped Up Pistons

The number and size of the pistons that a caliper employs is typically an indicator of the size of the calipers, pads and rotors. As rotors and pads get larger, so do the size of the calipers necessary to make use of the available friction surface. In order to evenly apply pressure to all of the available friction surface area, it becomes necessary to increase the number of pistons pressing on the pads. Sliding calipers employ a single, dual or even triple piston configuration, while fixed calipers feature an even number of pistons in an opposed configuration (pressing toward each other.)

 

IMG_0462

Cast, Forged, One Piece, Two Piece

Calipers are not only defined by their size but also their construction. Calipers are included among the components of unsprung weight and are subjected to a variety of conditions such as extreme temperatures and pressures. Thus, caliper design must take several variables into consideration.

3R1A9716_edited

The least sophisticated is the cast sliding caliper. Sliding calipers strike a balance of cost, weight and performance for the average streetcar. However, these calipers suffer from deflection and inadequate pressure under performance conditions, resulting in less than satisfactory results. The cast two-piece caliper features an opposed piston configuration that resists deflection while offering improved application of pressure to the brake pads. An even stiffer solution is the forged two-piece caliper. This fixed caliper shares similar design traits to its cast cousin, but benefits from being forged for greater strength and stiffness.

3R1A9727_edited - Copy 3R1A9729_edited - Copy

The stiffest and lightest solution, which also happens to be the most expensive, is the fixed, forged one-piece monoblock caliper. These tend to be machined from a forging of aluminum for strength and light weight. While offering the greatest performance, the cost to manufacture this type of brake caliper becomes cost prohibitive for all but the most well-funded of individuals or teams.

3R1A9705_edited

Piston Power

As mentioned earlier, calipers feature a greater number of pistons based on the size of the pads and the rotor. When increasing the pad and rotor size, applying equal pressure across the entire pad surface becomes essential for even application of pressure for optimal generation of friction. This can be achieved (up to a point) by way of larger pistons. When the caliper design calls for a lower profile to fit within the barrel of certain wheel sizes, adequate pad coverage can also be accomplished by way of additional pistons. Typical multi-piston configurations can range from four to six pistons with some designs employing up to as many as twelve pistons.

IMG_2172

The GT-R’s significant weight and output warrant the massive six-piston calipers that Nissan chose to use as standard equipment on its flagship sportscar.

Bigger isn’t always Better

So, when four is good, six is better and twelve is fantastic, right? Not necessarily so. Optimizing your brake system depends on a myriad of variables, including purpose, vehicle weight and power output, to name a few. There is such a thing as overkill, and overkill on brakes could actually compromise other aspects of performance like handling and feel. Brakes fall under the category of unsprung weight, which has a direct effect on responsiveness and overall feel. This is why a smaller and lighter vehicle like a first generation (NA) Mazda Miata that weighs in at just over 2,000 pounds would not benefit from the massive factory six-piston, forged monoblock brakes engineered for the 3,800 pound Nissan R35 GT-R. Not only would the Miata have to run much larger wheels just to fit this brake system, it would be far too much brake for the fly-weight Miata. The nimble feel of the NA would also be lost due to unsprung weight gained at each corner. Conversely, the much heavier R35 GT-R would brake as if it were in the vacuum of space while trying to stop with the NA Miata’s diminutive braking system. Exaggerated examples aside, a properly sized brake upgrade can lend greatly to vehicle performance. The right combination can improve feel, heat capacity and longevity while mitigating detrimental side effects related to unsprung weight. Ultimately, the right brake system upgrade for your ride will complement the overall build as well as its appearance.

IMG_3645

Sized Up: Brake Master Cylinder

Brake systems function on the mechanics of hydraulics, which is the use of fluid to perform mechanical force. In this case, the movement of the piston(s) in the calipers to apply pressure to the brake pads by displacing the pistons with brake fluid. The brake master cylinder forces fluid through the brake lines to each caliper to apply pressure to the pads. Since the amount of fluid displaced depends on the size and number of pistons, properly sizing the brake system includes evaluating the size of the brake master cylinder. When upgrading to a larger brake system, it is necessary to measure the displacement of the system to ensure that the brake master cylinder displaces enough fluid to deploy the pistons to press the pads against the rotor surface. Small bore brake master cylinders produce high pressure, while larger bore master cylinders deliver more volume.IMG_3643

Automakers go to painstaking lengths to properly size the brake master cylinder to the brake calipers they equip the vehicles with to ensure a balance of pedal feel and brake system performance. Properly sized, bolt-on brake systems should be designed to work with the factory master cylinder. If upgrading to significantly larger brakes, it is sometimes necessary to increase the size of the brake master cylinder to ensure that the feel and performance is not thrown out of balance.

IMG_2122 Cropped

Science of Stopping

Properly-engineered brake system improvements ranging from the most basic pad and rotor upgrades to full Big Brake Kits will enhance the feel from behind the wheel while delivering longer sessions on twisty highways or quicker lap times. While horsepower will make your car faster, balancing that horsepower out with improved braking performance will help you navigate the streets and the track safely and, in record time.

Ideal car meets are, at best, a fair weather experience. People lose interest quickly at the first sign of precipitation. When clear skies and warm temperatures are the first things to greet you as you walk out the front door, it’s a good bet that a great day and an even greater event await your arrival. This is especially true when the event is focused on the Nissan Skyline GT-R.

3R1A9462 edited

Skyline Syndicate, which started as a group of friends with a passion for all things Skyline, quickly gained momentum and evolved into a brand of its own. On Saturday March 11, a meet to celebrate Skyline Syndicate’s Launch Event took place in the City of Industry, California. With the support of the Purist Group, led by Sean Lee, this social media-promoted event drew import and European enthusiasts of all walks, in addition to the fortunate few that own Skylines.

Upon arrival, a walk through the parking lot gave attendees plenty to look at, including some gorgeous Supras, NSXs, BMWs and other desirable platforms. But the stars of the events were located close to the warehouse entrance. After passing a few R35 GT-Rs, we came upon a trio of R32 Skyline GT-Rs near the entrance to the warehouse.

Brake Systems 301: Increasing Torque, Friction and Surface Area

By Richard Fongstillen_u_banner_v1 (1)

Practice and experience lend to improving your driving skills. As you go faster and quicker, you will inevitably uncover more limitations of your vehicle’s hardware setup. In Brake Systems 101 and 201, we explored the basic bolt-on upgrades that help to improve initial bite, heat capacity and feel while retaining the stock calipers and rotor dimensions. However, even aftermarket upgrades have their limitations, especially when it comes to heat capacity, which leads to brake fade. This is where upgrading to a big brake kit could prove an effective solution.

IMG_0501

Physics of Braking

Braking is the conversion of kinetic energy (motion) into heat (and stopping power) by way of friction generated between the brake pads and the brake rotor surface. Put simply, the greater the friction produced, the greater the stopping power. However, with more friction comes more heat. While certain pad compounds thrive in specific operating temperature ranges, the collective brake system also has particular temperature requirements. Individual systems begin to fall short once their optimal temperature range has been exceeded. Increasing the temperature capacity by way of fluid upgrades and rotor cooling strategies are logical first steps. To take upgrades a step further, increasing the heat capacity by way of larger rotors and correspondingly larger calipers and pads add to the available rotor surface area and the size of the pads that can be used to generate friction.

Applying Torque for Better Braking

The application of torque is a matter of leverage. In the same way that increasing the amount of leverage by way of a breaker bar (torque arm) helps to increase the torque applied (moment of torque) to a bolt or nut, the same principle applies when increasing the rotor diameter and caliper size. Increasing the diameter of the rotor increases the torque arm and subsequently increases the moment of torque for braking. This is one of the significant advantages that a big brake kit has over a factory brake system.

art_shop_v2

The rotor on the left represents a factory brake. The rotor on the right represents a larger rotor as part of a big brake kit solution. Note that the increased rotor and pad not only offer greater heat capacity and increased friction surface area, it also has a longer torque arm. The longer torque arm translates into a greater moment of torque for improved braking performance.

Rotor Designs

Most vehicles come equipped with vented rotors up front, which help to facilitate cooling of the rotors in order to mitigate the potential for brake fade. A variety of vent types (radial, pillar and directional) have been developed in the pursuit of efficient rotor cooling.

DBA

Disc Brakes Australia (DBA) designed its custom “Kangaroo Paw” vent design with the intent of more efficient heat dissipation.

GTR_Vane_CutawayWeb450

 

KP_STRAIGHT

As mentioned in Brake Systems 101, the various brake pad compounds deliver varying levels of endurance, initial bite and resistance to heat. Pads designed for the street require little warm up and offer great initial bite, but sacrifice braking performance (reduction in friction under conditions of excessive braking and heat build up) when subjected to an endurance or heavy use situation. By contrast, an endurance race pad can take a lot of heat while maintaining optimal friction, but they must be heated to racing temperatures before becoming effective, which is unlikely to be achieved during normal street driving. Somewhere in between, there are pads that offer a balance of performance and endurance that suit a wider variety of driving situations.

Exotic Materials – STILLEN CCM-X Brake Upgrade

Technology and space-age materials have enhanced our world in many ways. When it comes to stopping, STILLEN and AP Racing have worked together to improve on the heavy yet nimble, Nissan R35 GT-R. Their efforts led to the development of the high thermal capacity (HTC) Carbon Ceramic Matrix brake rotor (CCM-X) that offers superior heat capacity compared to its iron counterpart. Once found only in the world’s most exotic sportscars, this is the first CCM rotor offering for a production tuner vehicle. In addition, STILLEN worked with Pagid to formulate its RSX1 pad material to offer easy bedding and greater performance for both street and track applications. During extreme performance testing at Auto Club Speedway, the HTC CCM-X rotors and RSX1 pads proved to run 142F cooler than previous generations of CCM rotors (1,346F vs. 1,488F), which validated the test results recorded on the brake dyno at AP Racing’s facilities in Coventry, England.

3R1A9595 Zoomed 2

IMG_2337

At the Limit

At this point the question is, how do you know when you’ve reached your brake system’s heat capacity? Since the friction between the pads and the rotor generates heat, this heat transfers into the components of the brake system (rotors, pads, calipers and brake fluid.)  If you’ve upgraded these basic brake system components with aftermarket components (as outlined in Brake Systems 101 and 201) and are still experiencing unresponsive braking and/or a spongy pedal feel after aggressive driving, you’ve likely reached the heat capacity of the brake system. This condition is referred to as brake fade.

IMG_2100

Don’t Get Faded

Brake fade occurs because the heat generated by the friction between the pads and the rotor has built up to the point that the pads are no longer able to create friction with the rotors (unresponsive braking) or pockets of air have formed in the brake lines due to brake fluid boiling (spongy pedal feel.) In both situations, heat is the culprit, which drives home the value of cooling the brake system. While adding brake ducts that direct air to the calipers and rotors certainly helps to facilitate cooling, increasing the amount of surface area available offers greater heat capacity and an increased friction surface area for use with larger brake pads and calipers.

radi-cal-full-kit-1

Understanding Big Brake Kits

As had been mentioned before, the factory equipment on most vehicles are selected as a compromise of cost versus performance – meaning that the vehicle manufacturer will offer you a safely adequate braking system necessary for your vehicle within their targeted budget. This opens the door to aftermarket improvements, and a big brake kit usually rides high on the list of upgrades. However, contrary to popular belief, upgrading to a big brake kit is not for the sole purpose of shortening stopping distances. Its greater merit is increasing the heat capacity of the braking system. A big brake kit increases the heat capacity of a braking system by incorporating larger rotors, larger pads and larger calipers. The increased surface area lends to greater heat capacity and an increased friction surface. (NOTE: Before investing in a big brake kit, consider the wheel size you are running, as some kits might require specific wheel sizing and offset to clear the rotor diameter and the larger brake calipers. Contact STILLEN for more information.)

IMG_0462

More Surface Area

Generally speaking, improving a brake system’s heat capacity typically requires more iron and thus, larger rotors. Larger rotors offer more material to absorb and dissipate heat, as well as a larger friction area for a larger brake pad to be employed. This is also why larger calipers are an integral part of the big brake kit (to be covered in Brake Systems 401). By increasing the amount of friction surface, more heat can be stored before reaching temperatures that cause fade. The increased heat capacity also increases the usable range brake pads have that would not have been practical on a lower heat capacity setup.

 

Mechanical Grip Improves Braking

While increasing the size of the brake calipers, pads and rotors inevitably improves the heat capacity and overall brake performance, a brake system is limited by another factor, mechanical grip. Mechanical grip refers to the tires, the only thing between your vehicle and the pavement, ground or terrain. In the case of road vehicles, the brake system’s ability to slow and stop a vehicle depends heavily on the tires. A vehicle with worn or inappropriate tires (i.e. endurance tires being used at a track day, rain tires when its dry, etc.) will not perform optimally compared to one fitted with tires suited to the purpose at hand.

Continuing on the subject of big brake kits, the next issue of STILLEN University, Brake Systems 401, will go into the benefits of larger caliper sizes and selection along with the mechanics of how they work.

Only the excitement of going to the track can get me up at 5am with enthusiasm. The STILLEN crew rose before the sun to make the trek out to Willow Springs International Raceway for the Boost Festival 2017 by Honeywell Garrett event. This multi-faceted event was run in conjunction with Global Time Attack, Just Drift and Drift 101. For the time attack fans, GTA conducted its first round for 2017 on the Streets of Willow, while JustDrift took over the Horse Thief Mile track where participants smoked some tires. For those interested in learning to drift or seeking to improve their drifting skills, class was in session at the Balcony as Drift 101 conducted lessons on how to get slideways.

Brake Systems 201: 2-Piece Rotors, Fluids and Lines

By Richard Fong

stillen_u_banner_v1

Upgrading brake pads and rotors can make considerable improvements to a vehicle’s braking system, especially since the factory equipment is generally adequate for an everyday street application but not always ideal for high-performance driving. However, there are a few other variables that can further enhance the performance of a factory brake system before making the jump to aftermarket calipers and larger rotors. Now that you’ve been familiarized with some of the first and most straightforward brake-system upgrades in our Brake Systems 101: Pads and Rotors, it’s time to look at the next modifications in line to optimize the factory brake system. Two-piece rotors, performance fluids and braided brake lines can further improve your factory brake system for greater performance on both the street and the track.

Room to Expand

A smoothly-operating vehicle typically indicates that all is well and functioning properly. When an ABS-like vibration feeds back through the brake pedal, it can be disconcerting to some and annoying to others. It’s certainly an indication of something amiss that requires attention. That vibration could simply be caused by uneven pad material built up on the surface of the rotor, for which a proper brake service (new pads, resurfaced or replaced rotors, brake fluid flush) would remedy. However, in the case of performance and heavy utility applications, the damage to the rotors could be more severe.

Dissipating Heat

A vast majority of brake rotors on the market are manufactured as a single piece of iron for cost and durability. As the friction surface for the pads, rotors are subjected to extreme heating and cooling cycles. Since the center or “hat” of the rotor bolts to the wheel hub, it is sandwiched between the hub and the mounting pad of the wheel. This limits the rotor’s ability to expand and contract freely when subjected to extreme braking conditions (as would be the case on a racetrack or during an aggressive mountain drive) and could lead to warped rotors. A viable solution would be to upgrade to a 2-piece rotor solution. In this application, a billet aluminum hat is fastened by way of “floating” hardware to a rotor, which permits the rotor to expand, contract and dissipate heat without being restricted by the hat. A 2-piece solution also permits the use of exotic and lightweight rotor materials as well, like a carbon-ceramic matrix.  An added benefit to having a billet aluminum hat and/or lighter rotors is reduced unsprung weight. This weight reduction helps to sharpen and lighten steering response which further lends to improved handling.

Boiling Point

A recurring theme in brake systems is that heat is the enemy. For the most part, this is true, the exception being specialized brake pad compounds formulated to function optimally at higher temperatures (racing brake pads). Aside from this instance, heat that is generated by the friction between the rotors and the pad material eventually transfers to the calipers and then the brake fluid. Modern brake systems are hydraulic, which means that they rely on incompressible hydraulic fluid (in this instance, brake fluid) to actuate the pistons against the pads when the brake pedal is depressed. The Department of Transportation (DOT) has established standards to indicate a fluid’s capabilities. DOT 3 brake fluid is the most common fluid used in automobiles. The name denotes the fluid’s heat capacity and performance capability as required by the DOT. Street vehicles rarely exceed the capabilities of DOT 3 fluid under normal driving conditions. When brake fluid heats to the point of boiling, pockets of air form in the brake lines. These compressible voids translate into a spongy brake pedal and an unresponsive brake system with dramatically reduced stopping ability. If you’ve upgraded your pads and rotors and have not upgraded the brake fluid, this could be the cause of poor braking performance. The solution is to upgrade your brake fluid. Under performance conditions such as on a track or a road requiring significant and frequent brake input, upgrading to DOT 4, DOT 5 or DOT 5.1 brake fluid will help to maintain the responsiveness and effectiveness of the brake’s hydraulic system.

DOT Standards

Typical factory brake fluid is engineered to function within a prescribed temperature range optimized for the majority of driving conditions that the manufacturer expects a vehicle to encounter. This covers a broad spectrum of conditions ranging from freezing to triple-digit ambient temperatures. While these requirements cover a seemingly broad range of temperatures, the brake fluid must endure far more extreme temperatures. DOT 3 fluid is the most common fluid type employed by automakers with some requiring DOT4 fluid (in the case of higher performance or heavy duty applications). DOT 3, 4 and 5.1 are polyethylene glycol based fluids while DOT 5 is silicone based. The hygroscopic traits (propensity to absorb moisture from the atmosphere) of the DOT 3, 4 and 5.1 fluids could render the fluids less effective over time. Regular flushing of the brake system mitigates this effect. The silicone-based DOT 5 fluid tends to cost more but benefits from its hydrophobic properties.

Fluid Grade               Dry Boiling Point                  Wet Boiling Point

DOT 3                                          401 F                                              284 F

DOT 4                                          446 F                                                311 F

DOT 5                                          500 F                                                356 F

DOT 5.1                                       500 F                                                356 F

Typical OEM rubber brake lines tend to expand under hard driving conditions, resulting in slower response and a spongy pedal feel.

Containing the Pressure

Another component of a factory brake system that could benefit from improvement is the brake line. The stock brake lines are often high-pressure rubber hoses designed to be flexible throughout the full range of travel for your suspension. However, during high performance braking, these factory lines tend to expand under extreme pressure, resulting in reduced responsiveness and braking performance along with a spongy brake pedal. To improve the responsiveness of the brake system hydraulics, swapping out the factory brake lines with performance brake lines is an essential upgrade. Performance brake lines (like those offered by Goodridge) feature a PTFE liner (inner hose) that is shrouded by a flexible sheathing (stainless steel or even exotic materials like Kevlar) that protect the liner and prevent expansion. This keeps the fluids moving toward the calipers, for more responsive braking under all driving conditions.

Stainless-steel braided brake lines like this Goodridge unit feature a PTFE liner for durability. The braiding helps to protect the liner from abrasion while also mitigating the expansion of the line under pressure.

Maxed Out

Now that you’ve learned about the basics of brake systems, you can maximize the stopping performance of your vehicle. Slowing and stopping are paramount for safety as well as performance, regardless of your application. From streetcars and track cars to tow and utility vehicles, a good braking system is a must. If you’re pushing your vehicle beyond these bolt-on solutions, you could be a candidate for a big brake upgrade, which will be covered in the next two installments of STILLEN University. Stay on track!

Automotive customization is really starting to hit the mainstream more often these days. You used to walk into a dealership, pick your color and a few options and that was the extent of the customization available at the dealer. However, things are changing, and for the better. More manufacturers and dealerships understand that consumers want their vehicle to be unique and reflect their personality. Automakers now offer more trim packages, color combos and more elaborate accessories than ever before. While this has satisfied a number of buyers, some dealerships realize that their customers wanted more.

Funding to modify a brand new vehicle often poses a hardship, as consumers generally spend a good amount on the down payment in order to make the monthly payments more palatable. Often times, this doesn’t leave a lot of cash for customization. Bennett Infiniti of Wilkes-Barre, PA understood the dilemma and decided to offer its customers the opportunity to drive off the lot with a customized ride. When this dealership modifies the car for you at the time of purchase with parts sourced directly from STILLEN, the cost can be rolled into your financing. This means you can add some nice modifications for approximately $40-$120/month (amount varies depending on cost of parts and labor).

Here is a great example of a modified Q50 Red Sport AWD that Bennett Infiniti put together. They installed the STILLEN Front Splitter, Side Splitters, Rear Diffuser and Wing to really give the Red Sport a more appropriate and aggressive appearance.

2017 Q50 Red Sport AWD STILLEN

The dealership informed us that the modified cars on the showroom floor always garner the most attention and it’s easy to see why. So next time you are in the market for a new car and want it modified, you know where to look!
