• Enhances drivetrain response and driver feedback.
  

The MMX Performance Differential Dual Mount has been purpose designed to reinforce one of the most crucial components of the G8x M2, M3 and M4 drivetrain. By utilizing the factory secondary bush mounting hole, it significantly increases differential stability under high-load acceleration and dynamic driving. Our solution adds a second point of support to improve rigidity, reduce unwanted movement and sharpen driveline response under load.

The mount offers OEM fitment with no modification required. It bolts directly to the factory differential with the factory sump retained, meaning there is no need to remove or replace the OEM sump and no fluids need to be drained. The mount can also be removed at any time and returned to stock, giving full flexibility to owners who want a reversible modification.

Designed for versatility, it provides perfect fitment with the OEM rubber bush (33 31 6 899 168), as well as with aftermarket polyurethane or solid differential bushes. By limiting excess movement of the differential, it also helps to eliminate diff and CV seal weeping during hard acceleration.

Ideal for track days, spirited driving or tuned cars, the mount helps maximize tire traction and enhance vehicle dynamics, delivering improved drivetrain response and sharper driver feedback.
