The Complete Diff System.
The MMX Ultimate Track Differential Kit (MMR55-0003) is the full diff mounting and protection package for the BMW G8x M2, M3 and M4, RWD and AWD. The Front Differential Lift Mount / Cradle (MMR55-1604), Dual Differential Mount (MMR55-1606) and two Rear Diff Raised Poly Bushes (MMR55-1605) lock the differential down at all four points, tightening up movement under load or, set to Lifted, raising the whole diff by 10mm to correct driveshaft geometry on lowered builds.
Alongside the mounting system, the High Capacity Diff Sump (MMR55-1600) replaces the OEM diff pan, giving more oil capacity and better cooling under sustained load, and the Drive Shaft Heat Shields (MMR55-1607) protect the driveshafts from the extra heat that builds up during hard driving. Bought together, this kit covers movement, geometry, heat and protection in one purchase.
Every part is matched at the same configuration, OEM with OEM, Lifted with Lifted, nothing mixed. This is the most complete diff setup MMX offers for the G8x M2, M3 and M4.
This kit contains:
1 x MMX Front Differential Lift Mount / Cradle (MMR55-1604)
1 x MMX Dual Differential Mount (MMR55-1606)
