The MMX Performance G8X M2 / M3 / M4 Ultimate Track Differential Kit brings together the full MMX rear differential package for the BMW G87 M2, G80 / G81 M3, and G82 / G83 M4. It combines the four-point differential mounting system with the High-Capacity Baffled Differential Sump and the Rear Differential Output Shaft Heat Shield Set, covering differential mounting, driveline geometry, oil capacity and cooling, and CV boot heat protection in one kit. It fits both RWD and xDrive models and can be installed at the factory differential height or in a +10mm raised position.
The MMX Front Differential Lift Mount / Cradle (MMR55-1604) replaces the factory front differential mount, the MMX Dual Differential Mount (MMR55-1606) adds support at the secondary bush location that goes unused in the factory setup, and two MMX Rear Differential Raised Poly Bushes (MMR55-1605) complete the four mounting points. In the +10mm position, the system corrects driveshaft geometry on lowered cars, reducing heat and premature wear on the CV joints and axle shafts.
The MMX High-Capacity Baffled Differential Sump (MMR55-1600) increases differential oil capacity by up to 2 liters (2.1 quarts), with an internal windage tray, internal and external cooling fins, and an additional -8AN port for an external differential cooler. The MMX Rear Differential Output Shaft Heat Shield Set (MMR55-1607) protects the rear output shaft CV boots from radiant exhaust heat.
