The MMX 380mm Front 2-Piece Floating Discs are a direct OEM replacement for the front brake discs on the BMW G8x M3 and M4, supplied as a matched pair with left and right-handed, two-piece floating rotors.
Each disc is lighter than the factory item and features larger, more efficient directional cooling vanes for even braking performance, more consistent pad wear and improved heat management under sustained track use.
