Purpose-Built for the Second Mount Point

The MMX Rear Diff Mount Bush (MMR55-1603) replaces the factory bush at the existing rear differential mounting point on the G8x and F8x M2, M3 and M4. Manufactured from 80A durometer grey polyurethane with a black anodised 6061-T6 aluminium sleeve, it fits directly into the OEM location with no modification required, tightening up the connection between the differential and the chassis and reducing unwanted movement under normal and increased torque loads. The result is a sharper, more stable driveline response under hard acceleration and dynamic driving, and a direct answer to the differential mount failures common on these chassis.

A second bush can be purchased to fit into the mounting point left unused from the factory, used alongside the MMX Dual Differential Mount (MMR55-1606). Together they add a genuine second point of support to the differential, further reducing movement under load. Bushes are sold individually, purchase a second alongside the MMX Dual Differential Mount (MMR55-1606) for the second mounting point.

Product Features

  • Direct replacement for the factory rear differential mounting bush.
  • 80A durometer grey polyurethane construction with a black anodised 6061-T6 aluminium sleeve.
  • Reduces drivetrain movement under normal and increased torque loads.
  • Direct fit with no cutting, drilling or modification required.
  • Minimal increase in NVH, suited to road and track use.
  • Answers the differential mount failures common on these chassis.
  • A second bush can be fitted alongside the MMX Dual Differential Mount (MMR55-1606) for a second point of support.
