MMX Performance 4-Point Diff Lift Kit for BMW M2 M3 M4 G8x

Four Points, Nowhere Left to Move.

The MMX 4-Point Differential Lift Kit (MMR55-0002) brings together everything needed to lock down differential movement on the BMW G8x M2, M3 and M4, RWD and AWD. The Front Differential Lift Mount / Cradle (MMR55-1604) replaces the OEM diff mount at the front, the Dual Differential Mount (MMR55-1606) adds a fourth mounting point BMW left unused from the factory, and two Rear Diff Raised Poly Bushes (MMR55-1605) take the rear positions. Bought as a kit, every part is matched, no guesswork over which pieces belong together.

Set to OEM height, the kit gives the differential nowhere left to move, tightening up every mounting point front, rear, top and bottom under hard acceleration and load changes. It's a significant step beyond the factory setup, which was engineered for comfort rather than control.

Set to Lifted, the same four points raise the whole differential by 10mm. This corrects the driveshaft geometry that gets thrown out on lowered G8x builds, taking the heat and premature wear off the CV joints and axle shafts that comes with running a lowered ride height. Every part is configured together at the point of fitting, matched at the same height throughout, nothing mixed.

For the complete build, the MMX Ultimate G8x Diff Kit (MMR55-0003) adds the High Capacity Diff Sump and Drive Shaft Heat Shields on top.

This kit contains:
1 x MMX Front Differential Lift Mount / Cradle (MMR55-1604)
1 x MMX Dual Differential Mount (MMR55-1606)
2 x MMX Rear Diff Raised Poly Bush (MMR55-1605).
