MMX Performance F8X M2 / M3 / M4 Dual Differential Mount

The MMX Performance F8X Dual Differential Mount (MMR55-1001) is engineered for the BMW F87 M2, F80 M3, and F82 / F83 M4 platform to add a second rear differential mounting point. Precision-machined from 6061-T6 billet aluminum, the mount increases support at the rear differential and helps reduce unwanted drivetrain movement under load.

The Dual Differential Mount can be installed in the OEM differential position with the factory bushings or paired with two MMX Rear Differential Polyurethane Bushings (MMR55-1603) for a firmer mounting configuration. When combined with the MMX Front Differential Lift Mount / Cradle (MMR55-1604), the differential can also be positioned 10mm higher to improve drivetrain geometry on lowered F8X applications.
