BMW E8x E9x Rear Control Arm Outer Poly Bush Upgrade - Powerflex Black Series PFR5-411BLK

Transform the back end of your BMW with the motorsport-ready Powerflex Black Series PFR5-411BLK. This rear control arm outer poly bush set uses a 95A race compound to curb unwanted arm movement, lock down toe control, and deliver razor-sharp chassis response. Ideal for track days, fast-road builds, drift, sprint and time attack, it is the go-to solution for anyone chasing precise alignment stability and repeatable handling under hard braking and cornering.
