The MMX Rear Diff OEM Bush Aluminium Insert Kit ‘Single Rear Mount’ (MMR55-1618) is engineered for the BMW G8x M2, M3 and M4, on both RWD and xDrive models. Fitted into the factory rubber differential bushes, the precision machined inserts fill the voids that allow the diff to move under load, tightening up the connection to the chassis without replacing the OEM bushes. The kit covers all five factory mounting points: four inserts for the front and one for the single rear mount. Paired with the MMX OEM Differential Dual Mount (MMR55-1606) and an additional MMX Rear Diff OEM Bush Aluminium Insert Single ‘Dual Mount’ (MMR55-1619), it supports the full dual rear mount setup. Precision machined from 6061-T6 billet aluminium, it’s a fully reversible upgrade.
