STILLEN has been offering carbon ceramic brake rotor upgrades
for the Nissan GT-R for several years. The 2012(US) Nissan GT-R upgraded the front brake rotors from 380mm to 390 mm, but went thinner from 34 mm to 32.8 mm. The
STILLEN/AP Racing CCM brake upgrade includes 400 mm x 34 mm front rotors, and 400 mm x 30 mm rear rotors. As a set, the CCM's are 38 pounds lighter than the factory rotors and hats. 38 pounds of rotating, unsprung weight.
DSport Magazine recently put a set of CCM's on their R35, as part of an entire package of weight loss, and exhibited it at the 2011 SEMA show.

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 20mm larger than the standard 380mm 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 brake upgrade kit includes:
• Front & Rear CCM brake disc/hat assemblies
• Front & Rear CCM-specific street & light track use brake pads
• Caliper spacers
• Active brake cooling package available for Track Users (Not Shown - Sold separately and can also be used with Iron Rotors)
