MMX 2-Piece Front Brake Rotors (370mm x 30mm) for BMW F2x / F3x BMW 1 Series, 2 Series, 3 Series, and 4 Series M Sport

MMX Performance’s 2-Piece Front Brake Rotors for BMW F2x and F3x 1, 2, 3, and 4 Series models offer a high-performance upgrade for vehicles equipped with M Sport brakes (blue calipers). Designed as a direct replacement for the factory 370mm x 30mm rotors, they ensure straightforward installation while delivering significantly improved braking performance on both road and track. Each rotor features MMX’s directional groove design for enhanced bite, superior heat dissipation, and reduced vibration or distortion under high thermal load. Compared to straight or drilled designs, these grooves generate less noise and help avoid fatigue cracking. Constructed with a two-piece design, the rotors utilize a high-carbon cast friction ring for improved thermal capacity and a lightweight aluminum center hat connected via a pin-drive system to minimize unsprung mass and maintain strength. Finished in a black zinc anti-corrosion coating, they combine functional endurance with refined aesthetics. R90 certified for street use, these rotors are sold as a pair, with optional matching rear discs available for a complete setup.
