[BMW M140i] REAR S/FRAME FRONT MOUNTING BUSH ANTI-SQUAT
PFR5-1220BLK is a full replacement bush for non-M models to raise the front of the rear subframe by 9mm, providing the same anti-squat characteristic during acceleration as featured on M model vehicles and is made using our Black 95A durometer material, providing the stiffest link between subframe and chassis, for hard track and motorsport use. For standard subframe alignment, without anti-squat, please use PFR5-420.
fitting Instructions can be found here.
