MMX Performance 2-Piece Front 380x36mm Rotor Set - BMW M2/M3/M4 (G8x) 2021+
Lease for as low as $/week
The MMX Performance 2-piece floating front rotor set is a direct bolt-on upgrade for the factory front discs on the G80 M3, G82/G83 M4 and G87 M2, provided your car came with the factory iron brake setup. It replaces the OE one-piece units with a true 2-piece floating design that runs cooler, weighs less, and resists the warping and judder that high-temperature track use can cause on stock rotors.
The 380mm x 36mm rotor rings are paired with separate hats so the ring can expand radially and axially under heat, instead of fighting against itself the way a one-piece rotor does. That floating construction is what dramatically extends pad and rotor life under repeated heavy braking, and is what allows MMX to engineer larger, more efficient directional cooling vanes inside the rotor casting, increasing cooling efficiency by up to 30% versus OE.
Real-world: lower steady-state and peak temperatures, less brake fade across consecutive hard stops, and a more consistent pedal feel session after session. Each pair is supplied as left and right-handed directional units, so vane geometry is always optimized to the rotor's direction of rotation. Pad wear stays even, brake performance stays predictable, and the rotors look the part of a serious upgrade.
The rotor face is slotted (J-hook style) to evacuate gas and pad material under heavy use without the surface-cracking risk that aggressive cross-drilling can introduce on iron. Each set is supplied as a left and right pair, bolt-on with no caliper, bracket, or pad changes required.
