AKG Performance Parts for BMW
BMW Rear Subframe Bushings, Poly 75D – F30, F32, F22
These BMW F30, F32, F22 Polyurethane (75D) Rear Subframe Bushings virtually eliminate subframe movement for effective power transfer through the rear-end. Rear subframe bushings are also the first step in maintaining proper rear-end geometry and alignment. The stock rubber subframe bushings deflect as torque moves through the drivetrain, allowing the entire subframe to move. Virtually eliminate rear subframe movement and start dialing in rear-end geometry with our BMW F30, F32, F22 poly 75d rear subframe bushings.
These extremely hard, race-spec 75D durometer polyurethane BMW F30, F22 subframe 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.
About Our 75D Polyurethane
Our U.S. Military Spec 75D durometer compound is as hard as a bowling ball, yet has elasticity and memory. This exclusive compound allows us to manufacture a bushing that has virtually the same performance as a solid bushing, but without the harshness on the chassis associated with solid metal bushings. Likewise, its elasticity and memory means they are also free from deformation which plastic bushings (Delrin, UHMW) are very prone to.
AKG bushings are the only aftermarket bushings for BMW molded in the USA in accordance to ISO 9001:2015 certified standards – the gold standard in manufacturing.
