MMX Performance Brake Discs REAR BMW F2x MMR30-0501R

MMR’s Performance Front Discs/Rotors make the perfect upgrade to your BMW F2x braking capability. Supplied as a pair of high quality, direct replacement 340mm x 30mm front discs that are a simple swap for your M-Sport factory originals, with matching rear discs also available.  Manufactured with the trademark MMR directional groove design and a black zinc anti-corrosion coating, these rotors will not only perform brilliantly in fast road and track use, but also look great under your alloys. 

The MMR Performance Front Discs/Rotors make the perfect upgrade to your BMW F2x M-Sport brakes (blue caliper) factory braking hardware. The 340mm x 30mm discs use the MMR directional groove design across the face for improved bite and debris clearance, plus helps to reduce distortion vibration during high temperature track day use.

In road use, these MMR directional grooves also generate less noise than straight or curved groove discs do, and don't suffer the fatigue cracking that drilled discs all too often experience after multiple heat cycles.

The two-piece disc (rotor) itself is made from high cast carbon - a mixture of high quality steel combined with carbon, giving a far higher friction coefficient compared to normal steel rotors. This is mounted via pin drive to an aluminium centre bell/hat.
