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.

The STILLEN R&D team discussing the difference in brake performance

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.

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.

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.

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.
