PowerFlex Rear Lower Control Arm Rear Bushings - E70, F15, F85, E71, E72, F16, F86

Product Details

In high-performance driving and competitive motorsport, deflection is the enemy of lap times. The factory rubber rear lower control arm bushings on BMW’s SAV/SAC platforms are a notorious weak link. Under heavy cornering, acceleration, and braking loads, the OEM rubber deflects wildly, altering rear-wheel toe and camber geometry mid-corner. To make matters worse, BMW does not sell these bushings individually; when the factory rubber fails, teams are forced to purchase costly, entire cast-aluminum control arm assemblies.

The Powerflex Bushing Set is an engineered, race-tier solution designed to reclaim chassis precision. Manufactured from Powerflex’s proprietary high-durometer polyurethane formulation, this upgrade eliminates unwanted suspension compliance, locking in your alignment geometry under the most punishing track and high-performance road conditions.

Engineered Performance Benefits:

• Deflection-Free Geometry: Dramatically minimizes dynamic toe and camber shifts during aggressive cornering, delivering predictable, razor-sharp rear-end rotation and maximum tire contact patch utilization.

• Cost-Effective Engineering: Eliminates the need to replace expensive, intact OEM aluminum arms just because a factory rubber isolated joint has failed.

• Advanced Material Science: Specially formulated polyurethane provides vastly superior resistance to oil, fuel, road grime, and ozone compared to standard rubber, ensuring zero performance degradation over time.

• Chassis Feedback: Sharpen your communication with the rear axle, allowing drivers to find the absolute limit of adhesion with total confidence.
