The Endurance-Focused XC3 BTCC Brake Kit
The standard braking system on the BMW E9X M3 is capable for road use, but repeated heavy braking can expose its limitations during track driving.
Long braking zones, increased vehicle speed, high-grip tyres and repeated heat cycles all place greater demand on the brake system. As temperatures rise, drivers may experience reduced consistency, increased pad wear and a greater risk of brake fade.
The XC3 BTCC Big Brake Kit addresses these limitations with a motorsport-derived braking package designed around increased thermal capacity, larger pad volume and consistent pedal response.
AP Racing CP9660 vs CP9668 - Both calipers share very similar architecture, with the main difference being that the CP9660 runs a 18mm thick brake pad and the CP9668 runs a 25mm brake pad
