AKG Performance Parts for BMW
BMW Rear Subframe Bushings, Poly 85A – E30
These BMW E30 Polyurethane (85A) Rear Subframe Bushings help to reduce subframe movement for improved 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. Tighten up this movement and and start dialing in rear-end geometry with our BMW E30 poly 85A rear subframe bushings.
These medium 85A durometer polyurethane BMW E30 subframe bushings are our street-spec compound bushings (as opposed to our performance-spec 95A compound). They are designed for those who want to retain a relatively comfortable ride with slightly improved performance over the stock oem bushings. Remember: the material used for the diff mount bushing location(s) must match the material used for the subframe bushings.
About Our 85A Polyurethane
Our U.S. Military Spec 85A durometer compound has elasticity and memory. This exclusive compound allows us to manufacture a bushing with superior performance characteristics that is free from the deformation which plastic bushings (Delrin, UHMW) are very prone to. Perfect for street-going cars which do not have large increases in horsepower over stock.
AKG bushings are the only performance bushings for BMW molded in the USA under ISO 9001:2015 certified quality standards – the gold standard in manufacturing. Our exclusive Mil-Spec polyurethane raw stock costs up to 5x that of the cheap poly and plastic used by others.
