The MMX Fast Road Performance Rear Brake Discs are engineered as the ultimate upgrade for BMW F2X & F3X models equipped with M Sport brakes (blue calipers). Designed as a direct replacement for the factory 345mm x 24mm discs, these rotors deliver superior braking performance, durability, and reliability for both spirited road driving and occasional track use.
Featuring MMX’s signature directional groove design, the discs improve braking bite, clear debris more effectively, and reduce vibration distortion under high temperatures. Unlike drilled discs, this groove pattern avoids fatigue cracking while also generating less noise than traditional straight or curved groove designs.
The advanced two-piece construction combines a high-cast carbon rotor for improved friction performance with a lightweight aluminium centre bell, mounted via a pin-drive system for optimal heat management and reduced unsprung mass. A zinc anti-corrosion coating on the centre bell and outer lip ensures long-lasting durability and a clean appearance.
