AKG Motorsport Differential Bushings, Poly 75D – E90 E92 (M3), E82 (1M)

Product Description These BMW E90 E92 (M3), E82 (1M) Polyurethane (75D) Differential (Diff) Mount Bushings eliminate virtually all differential movement for effective power transfer to the rear wheels. The stock rubber diff bushings deflect as torque moves through the drivetrain, which allows the differential to move. Eliminate virtually all of this movement and allow your diff to operate effectively with our BMW E90 E92 (M3), E82 (1M) poly 75D differential bushings. These extremely hard, race-spec 75D durometer polyurethane BMW E90/E92 M3 diff mount bushings are the hardest available (aside from solid aluminum). They are the best option for race classes where solid bushings are not allowed, or for those who do not wish to deal with the issues that may arise when using solid metal bushings. This is the proper durometer for high horsepower and/or big grip cars. Remember: the material used for the diff mount bushing location(s) must match the material used for the subframe bushings. Abou
