For Track and Motorsport use. The POWERFLEX Black Series bushes are manufactured using our Black 95 Shore A compound to provide maximum control of chassis geometry. They are designed for the Track, ready to Race and are engineered to be the best.
Polybushing is an easy way of dramatically improving suspension response without sacrificing too much in the way of refinement for your BMW!
On non-M models, this part raises the front of the rear subframe by 9mm providing the same anti-squat characteristic during acceleration as featured on the M-model vehicles. For standard subframe alignment, without anti-squat, please use PFR5-420.
Replaces OEM Part Number: 33312283382.
