This week we are adding four new part numbers to our new application listings for the BMW F82 M2, F80 M3 and F82, F83 M4.
We are grateful to Palmersport for helping us during the development of these parts. They run a fleet of rental M4’s and have experienced these bushes failing causing the diff to move and knock. Their cars are used extremely hard so they discovered the problem very quickly but it is obvious that this will become a common problem on track cars or as they age. Solve the problem before it occurs or simply tighten up the diff location using our easy to fit mounting inserts.
PFR5-4025 Rear Diff Front Mounting Bush is a replacement bush that includes aluminium sleeves with built in support to increase control of rear diff movement.
PFR5-4026 Rear Diff Rear Mounting Bush is another replacement bush that again features a built in support washer, providing further stability of the diff under acceleration.
PFR5-4027 Rear Diff Front Mounting Bush Insert fits into each of the original front mounting bushes, includes support washers and is a fast way to to increase the stability of the rear diff on bushes that are not worn or perished.
PFR5-4028 Rear Diff Rear Mounting Bush Insert fits into the voids in the original bush and is held in place by a large support washer to provide further stability and movement control.
These parts are also available in our Black Series range for those looking for a Track/Competition option.
