With the latest G8X M3/M4 having massive performance, grip and ability straight from the showroom, it’s no wonder they’re finding their way to the most serious of track days and tuning shops across the globe.

Whilst BMW are renowned for sporty and precise handling, front radius arm bushes have always been problematic from the factory on many of their vehicles. With ride compliance, chassis dynamicists and accounts teams fighting their respective corners, this bush is often a compromise on all fronts.

PFF5-2301 is made using Powerflex’s Black 95A durometer material and is supplied with outer shells to increase bush stiffness by 30% over OE, controlling longitudinal wheel movement under braking and cornering, and improving longer-term durability.

PFF5-2301 is not compatible with X-Drive models.
