MMX G8x High-Capacity Baffled Differential Sump / Oil Pan

Do you track your G8x M2, M3, or M4 RWD or xDrive? Our High-Capacity Baffled Differential Sump has been meticulously designed to keep your drivetrain performing at its absolute peak, even under the most extreme track and road conditions. Built for enthusiasts who demand reliability, precision, and maximum efficiency, our sump ensures that your high-performance G8x M-Car continues to deliver exceptional handling and control, lap after lap.

Maximum Oil Capacity, Cooling, and Efficiency.

Our sump increases oil capacity by up to 2 litres (2.10 quarts), providing a generous reserve to keep your differential optimally lubricated at all times. The integrated internal windage tray ensures constant lubrication of the gears and pinion while simultaneously reducing component drag. This careful design minimises drivetrain losses, allowing your car to maintain power delivery efficiency and prolong component life even under sustained high-stress driving.

Temperature management is critical for maintaining peak performance, which is why our sump features both internal and external cooling fins. These fins maximise the surface area for heat dissipation, helping to maintain consistent oil temperatures and prevent overheating. Whether on track or during spirited driving on the road, our sump ensures your differential operates at maximum efficiency, supporting reliable, high-performance operation.

Precision machined from 6061-T6 billet aluminium, our sump offers a perfect balance of strength and lightweight construction. Every surface, edge, and component has been engineered to the highest standard, delivering a robust upgrade that protects your differential, improves efficiency, and enhances the reliability of your M-Car’s drivetrain over time.

It features an additional -8AN port and includes an M22 to -8AN fitting adaptor, allowing the addition for external cooling setups.

Our baffled sump has been engineered to fit exactly like OE to existing factory mounts, providing a seamless upgrade without modification.

For those looking to further enhance stability, it is also designed to integrate perfectly with our Dual Differential Mount, requiring no additional hardware to attach to the High-Capacity Sump (MMR55-1606). This allows you to run the sump alone, the dual mount alone, or both together for the ultimate configuration.
