AP Racing

The BMW E46 M3 is probably one of the most iconic vehicles to come out of Bavaria. Not too long ago, Tony Jackson (Eibach Springs account manager) was in the process of selecting a new track vehicle to replace his Honda Civic which he had been racing, and winning championships with for almost 10 years. Tony wanted something rear wheel drive and figured he’d start with one of the best platforms available.


On the Track

In stock form, Tony was very impressed with the M3’s performance. Tony didn’t feel the car needed a lot to make it more competitive so he set out to add only the necessary modifications. Working for one of the largest suspension companies in the world, you can imagine what was worked on first. Tony worked with the Engineers at Eibach to develop custom rear shocks that he paired with Eibach Springs and Sway Bars. The improvements to the suspension helped push the M3 further along on the track, but there was still a major weakness in the car.



Slow down to go faster

Tony noticed after only a couple of track days that the stock brakes weren’t up to par saying, “I noticed that the pistons were seizing up from too much heat.” He elected to go with the AP Racing by STILLEN Radi-CAL Big Brake Kit. The forged Calipers, Bigger Pads, and J-Hook Rotors really allowed him to manage the heat in the brakes a lot better. This translated to being able to dive into corners much harder and not worry about brake fade well anymore.


The advantages of the AP Radi-CAL Brakes are quite extensive. The pressure forged calipers design is derived from the highly successful race Radi-CAL caliper. Utilizing an asymmetrical design the piston are positioned in a way to reduce torsional stress on the rotor as the pistons apply pressure under braking. This forging technique also allows for less material to be used than in traditional casting making the caliper lighter and stronger at the same time. The unique gives us the ability to have a larger brake pad annulus (radial contact patch) than normally found on similar big brake kits. This allows us to utilize more of the rotor surface increasing heat transfer and management (read more about it here).


The AP Racing Big Brake Kit comes with rotor options. For Tony’s racing focused uses STILLEN recommended the J-Hook Slotted Rotors. The patented design increases durability and performance. The J-Hook design gives you all the benefits of a drilled and slotted rotor without any of the downsides. Drilled rotors can potentially crack from rapid expansion and contraction while racing, and traditional slots create a less even heat distribution throughout the rotor. Because the J-Hook machining does not penetrate through the rotors and does not completely transverse them radially, they are phenomenal at withstanding harder driving and higher temperatures (read more about J-Hook Rotors here).


Tony gave us some lap time improvements of tracks that he frequents.

  • Buttonwillow Raceway – 0.7 second improvement
  • Chuckwalla Valley Raceway – 1.1 second improvement
  • Willow Springs – 1.5 second improvement
  • Laguna Seca – 2.4 second improvement
  • Streets of Willow – 2.7 second improvement

Everyone puts an emphasis on power, but a lot of people forget the slowing down (efficiently) can make you faster than some extra horsepower. Also consider the added confidence the driver has in their car knowing they can continually push to the limit and the brakes will be there to support them.

More power is still nice…

We don’t want anyone to think we are against adding power, and neither is Tony. That is why he went to our friends over at Magnaflow and commissioned them to build a high flow and light weight single exit exhaust to help the powerful 3.2 straight six breathe a little better. The whole system saved about 50 lbs and really helped open up the top end of the power band.


Wrapping it all up

All these modifications are great, but let’s not forget what makes all these upgrades useable. Connecting the all this horsepower, suspension, and braking performance to the ground are Nitto NT01’s wrapped around a set of Volk Racing forged ZE40’s.


STILLEN Partners with the best companies in the industry for all of our projects, so it is no surprise to see that Tony did the same with his M3. Tony is currently leading both Super Lap Battle and Global Time Attack series in points (for his class). This is one of our favorite examples of someone who understands that racing is about balance and synergy.

It’s that time of year again.. thousands are burning up the 30+ miles worth of carpeted aisles at the infamous SEMA Show in Las Vegas!  The STILLEN Team is no exception, with a big booth introducing the world to the new AP Racing Radi-CAL line of calipers used in the STILLEN-engineered Big Brake Kits.

AP Racing Radi-CAL Brake Caliper Launch at SEMA with STILLEN

These new Radi-CAL road calipers get there heritage from the racing Radi-CAL high performance calipers launched in motorsports in 2007, which have been dominating the likes of F1, F3, NASCAR and countless others.  This new caliper design features a 2-piece aluminum body with H-structure, and a non-symmetrical design developed to have a large reduction in mass yet improved resistance to braking torque.  Another benefit is increased caliper cooling surface without decreasing structural rigidity.

The list of amazing cars using AP RACING brakes continues to grow every day, we have touched on some of those vehicles before but today is a perfect time to highlight the ULTIMATE AP RACING equipped vehicle.

What makes it the ultimate? Other than the obvious name, how about it beating the Koenigsegg CXX around the Top Gear test track by over 4.5 seconds, and the Pagani Zonda R by over 5.5 seconds.  Yeah I’d say that pretty much makes it the ULTIMAte! Check the video below for the record breaking run:


If that’s not enough for you, how about some of these amazing photos by GF WILLIAMS that were posted today on Jalopnik.







For the rest of gorgeous photo shoot
Cruise over to Jalopnik:

Since today marks the unofficial start of the 2012 Tire Rack One Lap of America with the first drivers meeting of the year, we thought it would be fitting to highlight some of the vehicles running STILLEN products.

The One Lap of America is one of those racing series that is as equally bad ass as it is grassroots, as quoted from the One Lap of America website: ” The TIRE RACK ONE LAP OF AMERICA is the toughest 8 days of racing featuring the fastest street-legal cars on America’s most challenging racetracks.”

Ill sum up what makes this series so awesome in a couple short bullet points.

– Drivers must drive to 9 racetracks across the county to compete in Time attack, Drag and Skidpad events in the same car they will be competing in.

– Drivers only get ONE set of street radial tires (tread wear 140 or above)  to complete the 5000 mile journey and track events in.

-The driver with the most points at the end of 8 days wins


Very simple yet very intense.

Last year’s winner TOPSPEED motorsports ran our AP RACING J-hook rotors for their 2011 campaign, they loved them so much they decided to run them again this year.

TOPSPEED motorsports aren’ the only guys running the J-HOOK rotors… Forged performance opted for the tried and true formula as well.

I’m sure I’m missing a few other GT-R teams that are running STILLEN product so if any one has any info or news they want to sent over please have them email me at msabounchi@stillen.com

We wish everyone the best of luck and we can’t wait to see how this year turns out.


Remember a week ago when we told about those crazy Russian dudes from DRAGTIMES.info who race the best of the best in a standing mile for bragging rights? Well we stumbled upon a video from those guys today that is nothing less than amazing.

Like we mentioned earlier, these guys frequently take their GTR’s up to speeds well over 170mph. Slowing a 3800 lb car from those speed’s time after time will undoubtedly wreak havoc on the stock Brembo rotors and pads. It turns out, our R35 GTR Carbon Ceramic Matrix brake kit is a very popular option among these guys, because of their resistance to brake fade and warpage.  Watch the video below and you will understand why :).


(Note: Did any else notice the “rocket booster” mod on the GTR at the 3:04 mark of the video?)

Since we do have a special running our AP RACING products this month, I figured it would be fitting to give you 4 more reasons why AP RACING should be your first choice when it comes to Big Brake upgrades for your car.

Two year’s ago, ROAD AND TRACK magazine featured an article that immediately struck a chord with me and I still read that article to this day. They compared the fasted production cars on the road (at that time) vs. their ALMS beefed up twins. What made this article so interesting to me is that the cars in the ALMS (American Le Mans) field are completely based off their production siblings. The ALMS cars use the same motors, drivetrain, and body parts as their street car siblings that come off the assembly line, just much more beefed up. In fact, some of the racecars actually have LESS horsepower than their street ready siblings, go figure.

Because the ALMS cars are restricted to use the factory drivetrain layouts, and body componenets (plus some aero components) as their street siblings, you can imagine how competitive this series can be. In order to gain an advantage on the guy next to you, you have to make sure your car uses the highest quality components in every area possible. Every part of the car has to perform at the highest level and this includes the brakes. I was shocked to see that 4 out of the 5 ALMS cars tested dumped their factory big brake options and ran AP RACING.
First up we will start with Team BMW…
The AP RACING big brake upgrade is actually a very popular upgrade with BMW enthusiasts who frequently track their vehicles.

Next up, we have Ferrari… yes Ferrari! The F430 GTC Michelloto team opted to ditch their factory Brembo option and go with an AP RACING J-Hook upgrade.

Ferrari weren’t the only guys who opted to ditch Brembo for some AP RACING goodies…. Porsche also followed that tried and true formula.

Lastly, we have the extremely competitive Team Corvette…

IF you noticed the lack of a big AP RACING sticker on the side of these cars don’t be alarmed. That just suggests that these teams ACTUALLY paid for their brake set up and didn’t get persuaded into running something inferior in hopes of a kick back for a sticker placement.  If those aren’t 4 big reasons why you should consider AP RACING as your first choice for big brakes, I’ll leave you with this….  Since Formula 1’s inception in 1967 AP RACING has tallied up over 228 wins with cars running their brakes.  (That’s at least 5 wins a year since the beginning of Formula 1)
If you have any questions regarding applications for your specific vehicle, feel free to give us a call at anytime.
