BMW M4 Brake Kit - Rear - Alcon - 4 Piston Calipers + 380x32mm Rotors - Grey - `15-`27. A rear upgrade pairing Alcon RC4 4-piston calipers with 380x32mm two-piece rotors for consistent, repeatable braking.

Designed for the F8X M4 rear axle, grey RC4 calipers use staggered steel pistons for even pad wear, while stainless pistons help limit heat transfer to the fluid. Pin-mounted pads speed service, and the supplied high-friction pads increase stopping power. The 380x32mm two-piece rotors provide strong thermal capacity without excess weight.
