The MMX Performance G8X M2 / M3 / M4 3-Point Differential Lift Kit combines the two components needed to control rear differential movement on the BMW G87 M2, G80 / G81 M3, and G82 / G83 M4: the billet front differential cradle and the raised polyurethane rear differential bushing. The kit fits both RWD and xDrive models and can be installed at the factory OE differential height or reversed for a +10mm raised position.
The MMX Front Differential Lift Mount / Cradle (MMR55-1604) replaces the factory front differential mount and is precision machined from 6061-T6 billet aluminum. The MMX Rear Differential Raised Poly Bush (MMR55-1605) replaces the factory rear differential mount bushing with 80A durometer polyurethane, and its two-position center section sets either the factory height or the +10mm raised height. Both components install into the factory mounting locations with no modification required.
At OEM height, the kit creates a firmer connection between the differential and the chassis, reducing drivetrain movement under acceleration and changing loads without altering the rear driveline geometry. In the reversed "lifted" position, the cradle and rear bush raise the differential by 10mm. Lowering a G8X changes the operating angle of the rear driveshafts. Raising the differential by 10mm corrects that geometry, reducing heat and premature wear on the CV joints and axle shafts. The raised configuration is intended for lowered vehicles and works with both OEM and aftermarket axle shafts.
The 3-Point kit is the foundation of the MMX G8X differential mounting system. The MMX Performance G8X M2 / M3 / M4 4-Point Differential Lift Kit builds on it by including the Rear Dual Differential Mount and a second raised poly bushing in the additional rear mounting location that doesn't exist in the factory setup. The MMX Performance G8X M2 / M3 / M4 Complete Differential Kit adds a high-capacity differential sump and output shaft heat shields to the 4-Point system.
