BMW Rear Subframe Bushings, Aluminum – E46, Z4

These BMW E46, Z4 Aluminum Rear Subframe Bushings eliminate all 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. Eliminate rear subframe movement and start dialing in rear-end geometry with our BMW E46, Z4 aluminum rear subframe bushings.

Although our solid aluminum BMW subframe bushings are the hardest available and have a longer life span than other bushings, they are also extremely harsh and unforgiving on the chassis. Cracks may occur around the mounts. Any area using aluminum bushings should be reinforced and consistently checked before/after each race. 

Made of solid CNC’d 6061- T6 aluminum. Engineered for a perfect fit. Set of four subframe bushings. Remember: The material used for the subframe bushing location(s) must match the material used for the diff mount bushing(s).
