The Ultimate G8x Diff Collection.
The complete MMX differential system for the G8x M2, M3 and M4. Reduce drivetrain movement at stock height, or correct axle geometry on a lowered build, then scale up to a full 4-point setup with the Dual Differential Mount, High Capacity Diff Sump and Drive Shaft Heat Shields.
Don’t be baffled. Be protected.
MMX’s high-capacity baffled differential sump is engineered to maintain consistent oil control under extreme load, keeping your G8x M2, M3 or M4, RWD or xDrive, performing at its peak on track and road. Built for drivers who demand reliability and precision, it delivers the confidence to push harder, lap after lap.
2 litres
Increases oil capacity by up to 2 litres (2.10 quarts) for optimal differential lubrication at all times.
6061-T6
Precision machined from 6061-T6 billet aluminium for a perfect balance of strength and lightweight construction.
Windage
Integrated internal windage tray ensures constant gear and pinion lubrication while reducing component drag.
What's new.
The MMX Front Differential Lift Mount / Cradle (MMR55-1604) is engineered for the BMW F8x and G8x M2, M3 and M4. Fitted on its own in the OEM position it reduces drivetrain movement under load, on road or track. Paired with the MMX Rear Diff Raised Poly Bush, it raises the differential by 10mm, correcting driveshaft geometry on lowered vehicles and reducing heat and premature wear on the axle shafts. Precision machined from 6061-T6 billet aluminium, it's a direct replacement requiring no modification.
If you already run the MMX High Capacity Diff Sump (MMR55-1600 for G8x, MMR55-1000 for F8x) and/or the MMX Dual Differential Mount (MMR55-1606 for G8x, MMR55-1001 for F8x), the Front Differential Lift Mount / Cradle is the natural next step to complete the setup.
