The MMX Rear Diff Mount Bush (MMR55-1603) is a direct replacement for the factory rear differential mounting bush on the BMW G8x and F8x M2, M3 and M4. It reduces movement under load at the rear differential mounting point and directly addresses the differential mount failures common on these chassis.
Manufactured from 80A durometer grey polyurethane with a black anodised 6061-T6 aluminium sleeve, the bush is engineered for durability under sustained load, whether on road or track.
