The MMX Fast Road Performance Front Brake Discs are a premium upgrade for BMW F2X & F3X models fitted with M Sport brakes (blue calipers). Designed as a direct replacement for the factory 340mm x 30mm front discs, they deliver improved stopping power, durability, and heat management for both spirited road driving and occasional track day use.
These discs feature MMX’s signature directional groove design, providing sharper braking bite, faster debris clearance, and reduced vibration distortion at high temperatures. Unlike drilled discs, the grooved design avoids fatigue cracking and produces less noise compared to straight or curved groove alternatives.
Constructed using an advanced two-piece design, the discs combine a high-cast carbon rotor for superior friction performance with a lightweight aluminium bell/hat mounted via a pin-drive system. A zinc anti-corrosion coating on the centre bell and outer lip ensures long-lasting durability and a clean finish, even after repeated heat cycles.
