Powerflex Black Series PFR5-412BLK Rear Upper Control/Camber/Top Arm Outer to Hub Carrier Polybush 95A – BMW 1 Series E8x (E81 E82 E87 E88) & 3 Series E9x (E90 E91 E92 E93) incl xDrive – Polyurethane Wishbone/Link Bush Kit

Powerflex PFR5-412BLK Rear Upper Arm Outer Polybush Kit for BMW E8x and E9x

Dial in rear end precision with this track-focused polyurethane bushing set from Powerflex, part number PFR5-412BLK. Built in a high-durometer 95A compound for motorsport use, these rear upper arm to hub carrier bushes lock down geometry to keep camber and toe stable under hard cornering, braking and acceleration.

If you want a sharper, more planted BMW on fast road, circuit or drift days, this is the go-to rear axle upgrade. Expect crisper turn in, cleaner feedback from the chassis and far less compliance than old rubber mounts. We run these bushes on our own builds at MJ modifications and customer feedback has been outstanding for consistency and durability.
