Stillen has just released some more information on the AP racing/Stillen 400 mm carbon ceramic matric brake rotors and pads for the R35 GT-R. Pricing has not been released yet.
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 (Not Shown - also sold separately for non-CCM equipped GT-R’s) Source : Stillen
Once found only on the world’s most exclusive supercars, Carbon-Ceramic Matrix (CCM) brakes have been developed for the first specifically tuned aftermarket application – the 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, improving performance in all categories: acceleration, handling and braking.
AP Racing CCM discs are the next technological platform after almost three decades of using carbon-carbon brakes on racing vehicles (even longer on fighter jets). Advances in materials, process technologies and nanoparticle technology make it possible to use a special carbon fiber precursor along with new, patented process techniques. This precursor is converted first into 3-Dimensional, multi-directional continuous carbon fibers then to carbon-carbon (via methane cracking during infiltration by pyrolysis) and finally to carbon silicon carbide (CSiC). We call it Carbon-Ceramic Matrix, or CCM for short.
