STILLEN Announces CCM-X – The next generation of Carbon-Ceramic Matrix Brakes for the Nissan R35 GT-R

The STILLEN R&D team continues to develop industry-leading performance products with long-standing technical partner AP Racing. Their hard work has resulted in the release of the next generation in Carbon-Ceramic Matrix (CCM-X) brakes for the Nissan GTR. This kit utilizes a new High Thermal Capacity (HTC) process which helps pull the heat from the CCM disc surface deeper into the 3D core to allow the discs to operate cooler through more efficient use of internal venting and air flow.

We have also homologated a new Pagid RSX1 pad material designed specifically for our new CCM-X discs for easier bedding and higher performance, these pads are ideal for use on the street and for track days.

The CCM-X disc assembly hardware has now been updated to include anti-rattle springs that still allow the full benefit of a floating disc, yet eliminates the “noise” associated with this style of disc.

During extreme performance testing at Auto Club Raceway in Fontana, CA, performing back-to-back repetitive testing runs pushing the limits of brake temperatures, the new combination of HTC CCM-X discs and Pagid RSX1 pad material reduced disc temperatures from an average of 1488F to 1346F, that’s 142 degrees cooler than the previous generation CCM. These real-world tests confirmed the results of our brake dyno testing at AP Racings lab in Coventry, England.

Once found only on the world’s most expensive supercars, Carbon-Ceramic Matrix (CCM) brakes have been developed for the first specifically-tuned aftermarket application – the Nissan R35 GT-R. These 400mm disc assemblies are larger than the standard OE iron discs, yet reduce weight by nearly half. This is rotating and unsprung weight, leading to improvements in all performance categories: acceleration, handling and braking.

After three decades of using carbon-carbon brakes on racing vehicles (even longer on fighter jets), AP Racing CCM discs are the next technological platform. Advancements in materials, process technologies and nanoparticle technology make it possible to use a special carbon fiber precursor along with new, patented process techniques. The unidirectional precursor is needled into a 3-Dimensional, continuous carbon fiber preform. This differs from lower cost technologies that use loose, chopped strand fibers and thin woven face plies bonded on as a friction surface. A true 3D matrix is stronger, more robust and provides longer life than the more brittle alternative. As a comparison, think quality hardwood versus particle board or MDF with a veneer.

Converting the 3D preform to carbon-carbon is done under high heat and pressure via methane cracking during a special carbon vapor infiltration (CVI) process. After initial machine work, a final conversion process results in a full matrix carbon-silicon carbide (CSiC). We call it Carbon-Ceramic Matrix, or CCM for short. The discs are then sent through the final machining, grinding, and balancing. Of course, the CCM discs are now so hard that only special diamond tooling can be used!

Who uses these ultimate CCM discs? The most up-to-date version is found on the Koenigsegg CCX and McLaren MP4-12C. And now – STILLEN and AP Racing have optimized a specific set for your R35 GT-R and its factory brake calipers.

The STILLEN-AP Racing CCM-X brake upgrade kit includes:

  • Front & Rear CCM-X brake disc/hat assemblies
  • Front & Rear Pagid RSX1 street & track use brake pads
  • Caliper spacers
  • Active brake cooling package required by Track Users (Not Shown – Sold separately and can also be used with Iron Rotors)

Note: Due to the dramatic reduction in overall mass, brake temperatures will run higher than the O.E. iron disc system given the same usage. STILLEN strongly recommends using AP Racing PRF brake fluid, one of the best high temperature fluids available. PRF is used in the most demanding Motorsports applications around the world.

Today was the first  day of actual racing.  It was a great day and Jen and Steve did a fantastic job.  Their still getting to know each other’s styles and figure out what the other one wants to say as well as hear.  It always takes a bit of time to develop that relationship between driver and co-driver.

 The car is running well.  We’re ending the night in Whangarei (“wonG uh ray” or “phonG uh ray” if you say it the Maori way).  We’re very excited to be on new roads this year.  It really helps level the playing field.  When the organizers put these events on they have to get the approval from every single person who lives on the roads we’re going to be racing on.  It takes about five months and they see around 9,000 people.  It’s truly impressive and even more impressive that they were able to branch out to new parts of the country!  Peter Martin and the crew at Targa New Zealand have worked hard to put on the best possible event!

Conrad and I did quite a lot of traveling today and got to see three stages!  Got some great action shots as well as a few “uh oh” moments from some of the competitors.  Steve has been up and down in the standings all day.  The first couple of stages were a bit rocky but later in the day they started making some great times and even beating some of the front runners like Tony Quinn.  It’s still very early in the race though.

Wish us luck and follow along as the rally continues!

One of the more popular products we make for the Nissan GT-R has been the polyurethane Protective Skid Plate, and with the changes to the new 2012 GT-R’s front lip, this required a new skid plate to be designed. Proud to announce we are in final development of the new version for the new model!

Here’s a sneak peek inside the STILLEN modeling shop located in Costa Mesa, CA, and shows the final piece test fitted on the car before we sent it into mold preparation.  The final production part will be black urethane, sprayed with a black matte paint, and can also easily be painted to match any specific color if desired.

The skid plate is designed to protect the extremely expensive front fascia from scrapes and light bumps. It follows the specific contours of the car, and installs in just minutes with everything needed supplied.

We are in full swing with the 2012 Nissan GT-R, and are also nearly finished with the Front Lip Spoiler, as well as the Aerodynamic Side Skirts which are also available for the 2009-2011 GT-R.  Look for more information soon.

We’ve also been doing product fitment on other STILLEN items, such as our Cat-Back Exhaust System, Secondary Cat-Delete Y-Pipes, Stainless Steel Brake Lines, AP Racing rotor upgrades and much more!

We recently worked with Truckin’ Magazine on some high speed brake testing, putting the AP Racing BBK designed by STILLEN to the ultimate test at El Toro Marine Base.

Truckin’ editor Dan Ward pushed their 2004 GMC Sierra “Project Novakane” to the limit with repeated 80-0 mph stops beginning with the factory setup, swapped brake systems, and repeated the aggressive testing on the truck after outfitting the AP Racing setup onto the truck.

Below is an excert from the article with performance data from their extensive testing:

Truckin’ Magazine – October 2010 Issue

“Rather than test the truck from 60 mph, we hit the ‘whoa’ pedal at 80 mph, after all, do you really drive 60 mph on the freeway? Factory braking performance was dreadful, as a combination of grooved rotors and newish pads made for chassis vibrations when stopping and a weak pedal. After bolting on the 20-inch wheels and tires to the Sierra, the sticky Nitto tires actually improved the stopping distances, which confused us at first, but then we released the overall weight of the new wheels and tires wasn’t much heavier than our OE combo.

GM touted the redesigned ’99+ fullsize trucks as having the best brakes in their long history of building trucks. That’s nice marketing hype, but GPS data acquisition doesn’t lie and the new AP Racing brakes are the double-D cups to the OE’s training bra. We weren’t surprised to have better overall stopping power, after all, that’s what we expected from a company with a rich racing heritage, but what did surprise us was the pedal feel. Without being touchy, the brake pedal is now very linear with minimal inputs doing an impressive job of bringing the 4,300-pound truck to a standstill. As expected, the aggressive brake pads are heavy on the dust, which provides us another excuse to wash the wheels/tires more often. This upgrade was expensive, but unlike in many cases, you actually get what you pay for from Stillen.

With the AP kit bolted on, we made several 80-0 mph test runs and came away with an average of 226 ft, more than 144 ft than better than stock. That’s equivalent to stopping in only 5.56 school buses or basically stopping before going through an entire intersection and saving the lives of more than 350 kids in those buses.

Also, the green AP heat paint that was applied to the stock rotors burned white, meaning they exceeded 430 degrees Celcius during hard braking, but the new AP rotors didn’t burn through the green paint. This translates into the drilled holes and vents doing their job by keeping the rotor surface cooler, longer. If safety and performance are high on your list, bringing your truck to an immediate halt doesn’t get much better than with AP Racing’s bolt-on big brakes.”

FOR IMMEDIATE RELEASE

STILLEN OFFERS NEW AP RACING
2008-2010 BMW M3 (E9x)
FRONT AND REAR BIG BRAKE KITS

Features innovative Strap Drive System for road and track day applications

Costa Mesa, Calif. AP Racing, the braking technology choice of professional race teams worldwide (including Rahal Letterman IMSA ALMS GT2 M3, BMW Motorsports FIA GT2 M3, etc), has introduced front and rear Big Brake System for the 2008-2010 BMW M3 (E9x). Available from the Brake Pros product division of STILLEN, these new brake upgrades fit most 18″ and 19″ OE wheels. They are compatible with OE ABS, traction control, stability systems and factory brake master cylinder.

Front systems may be ordered with AP Racing’s newly updated 6-piston CP5555 calipers finished in black (AP7100), red (AP7100R) — or — limited-edition Comp Gray (AP7100G). For optimum mechanical and thermal balance, complimentary rear systems are advised. The rear systems are supplied with AP Racing’s new CP5306 4-piston calipers in matching colors (AP7150 / AP7150R / AP7150G).

Manufactured for maximum stopping power and minimum brake fade, the kit offers high performance braking capability with race proven technology and comes complete with calipers, rotors, brake pads, coated stainless steel braided brake lines and all necessary mounting hardware for immediate bolt-on.

Two-piece modular rotors float on an aluminum hat and have 72 directionally curved vanes to maximize cooling in extreme brake situations. Both front and rear rotors are available in a cross-drilled and slotted pattern for an aggressive pad bite and better face cooling or can be purchased slotted only for aggressive track use. The AP Racing Strap Drive System has been developed for both road and track day applications. It uses a series of stainless steel straps to locate the disc to the mounting bell, producing a flexible coupling between the hub and the disc faces. This allows the disc to run true in the caliper under all conditions and also permits the disc to expand and contract without being restricted.

Strong, durable and designed to withstand any punishment, AP Racing Brake calipers are manufactured with a lightweight, pressure cast aluminum alloy 2-piece body and finished with a hard anodized 2-part paint finish. This 2-piece design is more rigid than commonly available monoblock calipers. Differential piston bores eliminate pad taper and maximize braking efficiency, and the anti-rattle clip eliminates pad knock and noise. A fixed radial mount ensures minimal caliper flex for the best available brake feel under all operating conditions.

A little while back we had a chance to meet up with Matt Farah and his awesome crew from TheSmokingTire.com and show them around the buildings here at STILLEN.

Matt and Steve then jumped in the bright orange STILLEN GT-R and took a run through some of the local canyons.  See below for the video!

Matt started The Smoking Tire video series last year, and previous to that was the driving force behind Garage419. Two minutes with him is all it takes to recognize that he’s a true car enthusiast, and he’s as genuine as he comes across in his videos. Be sure to check out and subscribe to his video series here.

This Strap Drive System has been developed by AP Racing both for Road and Race applications. The standard fitment brake discs on many performance cars can suffer from brake vibrations caused by disc distortion. This generally occurs on fast road and track installations.

On many performance cars the typical standard brake disc will be a heavy duty ventilated single piece casting. Couple this type of rigid disc to a standard hub and wheel bearing and the result is any hub distortion / run out will transfer onto the disc brake faces. This eventually results in brake vibrations, usually picked up through the steering wheel.

The AP Racing Strap Drive System offers a new take on the floating systems already in the market place. Strap Drive uses a series of stainless steel straps to locate the disc to the mounting bell, producing a flexible coupling between the hub and the disc faces. This allows the disc to run true in the caliper under all conditions and also permits the disc to expand and contract without being restricted.

Some current replacement discs in the market place have evolved from Motorsport applications, they typically use a drive bobbin to provide some disc float and were devised to reduce pad knock off on race cars. This system can work on a road application but there are some major drawbacks that the Strap Drive has overcome with its simplicity.

Bobbin float discs rely on a series of drive bobbins moving freely in drive slots. This movement can create wear during service and promote noise. The slots can fill up with road / brake debris causing them to seize. AP Racings strap couplings can’t suffer from any of these drawbacks. Therefore Service life, brake noise and also brake pedal travel are all improved.


Benefits / Features:

  • Compared with single piece discs the disc is de-coupled from hub, this allows disc to align itself perfectly within the caliper.
  • Improved pedal feel and brake response as a result of improved disc alignment within caliper.
  • Improved pedal feel at elevated temperatures as disc rotor is able to expand in a controlled manner with little influence from the disc mounting. This greatly reduces disc coning.
  • Controlled axial float of disc rotor reduces brake ‘knock-off’ which can result in an inconsistent pedal feel.
  • No free moving parts means that the wear problems normally associated with floating disc designs is not present.
  • No free moving parts means that there are no clearances to become clogged with debris and corrosion which would prevent a conventional floating disc from operating correctly.
  • No free moving parts means no unwanted mechanical noise from discs.
  • Disc rotor and strap sub assembly available as service item for cost effective servicing.
  • Successfully used in race applications.

Important note: When replacing brake pads with strap drive discs fitted, do not push the pistons back in to the caliper by use of a lever against the discs. If this is done then the disc straps may be distorted and this can cause disc runout, resulting in possible brake vibration.

Steve Millen and the R&D crew here at STILLEN are at full throttle wrapping up the build of the STILLEN GT-R, and Road & Track has been continuing their great video coverage of the build and testing.

These three videos bring the total to 16 videos surrounding the STILLEN GT-R and the build for the Targa Newfoundland Rally which is in mid-September and quickly approaching.
