MMX Performance G8X M2 / M3 / M4 4-Point Differential Lift Kit

The MMX Performance G8X M2 / M3 / M4 4-Point Differential Lift Kit locates and secures the rear differential of the BMW G87 M2, G80 / G81 M3, and G82 / G83 M4 at four mounting points. It combines the billet front differential cradle, the Dual Differential Mount, and two raised polyurethane rear differential bushings, fits both RWD and xDrive models, and can be installed at the factory differential height or in a +10mm raised position.

The MMX Dual Differential Mount (MMR55-1606) adds an entirely new support structure for the differential and connects at a secondary bushing location that goes unused in the factory setup, creating a fourth point of contact for the rear differential.

The MMX Front Differential Lift Mount / Cradle (MMR55-1604) and the Dual Differential Mount are CNC machined from 6061-T6 billet aluminum. Both MMX Rear Differential Raised Poly Bushings (MMR55-1605) are 80A durometer polyurethane with a two-position center section that sets either the factory height or the +10mm raised height.

At OEM height, the four mounting points reduce differential movement under acceleration and changing loads, which also helps prevent the differential and CV seal weeping that excessive movement can cause. In the +10mm position, the system corrects rear driveshaft geometry on lowered cars, reducing heat and premature wear on the CV joints and axle shafts.
