Millway Motorsport Dual Mount Diff Lift Kit, Street Version. This kit is suitable for F87 M2, F87 M2 Competition, F80 M3, F82/F83 M4.
It is commonplace for lowered or hard-used examples of these cars to encounter damage to the differential cooling fins. With Millway’s Diff Lift Kit, the differential is not only raised out of harm’s way, but improvements are made to the driveshaft geometry too. Another problem, especially with increased power levels, is to damage the original single differential rear bushing. BMW updated the bushing spec to help with this, however there is a second differential bush mounting location on the original subframe – making use of this is the key to maximum reliability and torque capacity.
Millway’s billet rear diff hanger makes use of the second differential mounting location, and is also supplied with the updated BMW rear bushes – choose one bush if your car already has the updated plastic bush, or two if you have the original design rubber bush. The Millway parts are machined from billet aluminium at their Swedish HQ. Differential front mounting bushes and bolts are also included.
