MMR Performance Rear Brake Discs Rotors 345mm x 24mm for BMW F2x F3x with M Sport Blue Calipers – Fast Road and Track Day Upgrade
Upgrade your BMW F-Series braking with MMR Performance rear brake discs rotors. Designed for BMW F2x and BMW F3x models with M Sport Performance brakes blue calipers, these 345mm x 24mm rear discs are a high quality, direct replacement that deliver stronger bite, improved pedal feel and fade resistance for fast road and track day driving. The distinctive MMR directional groove design enhances pad bite and clears debris, while the black zinc anti corrosion coating keeps the hubs looking smart behind your alloys.
These slotted rear discs use a high carbon casting and a two piece rotor construction with a pin drive aluminium bell hat for stable performance under repeated high temperature use. On the road, the MMR groove pattern runs quieter than straight or curved grooves and avoids the fatigue cracking often seen on drilled discs. Public highway legal and R90 approved, this is the ideal BMW F20 F21 F22 F23 F30 F31 F32 F33 rear brake disc upgrade for drivers who want OE fit with motorsport inspired performance.
