MMX 2-piece 380 mm floating front brake discs for BMW F8x M2, M3 and M4
Upgrade your BMW F8x brakes with MMX 2-piece 380 mm floating front discs, the ultimate performance brake discs and rotors for BMW M2, BMW M3 and BMW M4 owners who demand stronger stopping power, cooler running temperatures and long-term reliability. These 380 mm discs run up to 30 percent cooler than OE and increase cooling efficiency by up to 30 percent, delivering consistent performance on fast road and track days.
F-series M cars have a capable factory front brake setup, but the OE 380 mm drilled discs can suffer when driven hard. MMX solves this with a two-piece 380 x 30 mm floating design that allows the disc and hat to expand radially and axially under heat. This design helps prevent warping and cracking that single-piece discs are prone to, while improving pedal feel and confidence. The grooved friction face increases initial bite, clears gas and debris from the pad, and balances brake feel with pad and disc longevity.

Real-world results
We have run these MMX 380 mm floating front discs on our own cars and with customer vehicles on road and track. Feedback is consistently positive, with stronger initial bite, improved pedal feel and far better heat management that reduces fade and helps pads perform as intended.
Pad compatibility
These discs work with OEM pad compounds and aftermarket performance pads. For regular road use the factory pad compound performs very well thanks to the improved cooling. For sustained circuit work consider a track-oriented pad to match your driving style.
