Carbon ceramic brakes used to mean a five-figure factory option you had to tick on day one. The MMX Performance 2-Piece Carbon Ceramic Front Rotor Set converts a G8X M car with factory iron brakes to carbon ceramic discs, using your existing calipers, brackets and hardware.
No caliper swap, no bracket changes, no recalibration. Just a massive cut in rotating mass and brakes that shrug off repeated hard stops.
Carbon Ceramic Front Rotor Conversion for G8X M Cars
Each 380 x 36mm disc weighs 6.9 kg, 46% less than the factory steel rotor. That is unsprung, rotating weight coming off the front axle, so steering sharpens and the suspension works less. The 2-piece floating design pairs the ceramic ring with an anodized black hat, letting the ring expand under heat instead of warping or cracking.
