Bushing Kit, Rear Upper Control Arm, Inner, BMR, 2008-09 Pontiac G8

Decrease spindle counter-rotation under acceleration by upgrading your OE rubber upper control arm bushing with a high durometer BMR polyurethane bushing upgrade. This bushing is very soft from the factory and has a lot of leverage placed on it during aggressive shifting. During testing, BMR observed severe deflection in this bushing which permitted the rear uprights (spindles) to counter-rotate excessively during a launch or other high load situations such as shifting. These bushings successfully reduce this movement, providing more consistent and predictable load transmission to the tires.
