MMX BMW G8X 2-Piece 370mm Floating Rear Brake Discs/Rotors (G80/G81 M3, G82/G83 M4 & G87 M2)

MMX Performance BMW G8X rear brake discs are designed to directly replace your OEM brake discs and come complete with left and right-handed, two-piece floating discs. Each disc features much larger, more efficient directional cooling vanes to ensure even braking performance, pad wear and cooling capability.

Designed specifically for the BMW G80 M3, G82 M4 and G87 M2, the MMX 370mm x 24mm 2-piece floating rear discs are the perfect addition to match our MMR front replacement discs. Matching grooves, matching performance.

Superior Brake Disc Design

Utilising a two-piece 370mm floating design allows the MMX disc and hat to expand radially and axially as they absorb heat generated from use, avoiding the most common cause of warping and cracking seen in single-piece discs. Due to the efficiency of this design, MMX discs last considerably longer than factory discs. The friction surface features MMX's trademark groves that increase bite and remove debris from the pad surface giving the perfect balance between brake feel and longevity.
