Arm Bush BMW Z4-series (E89)

PFF5-401 Front Radius Arm to Chassis Bush uses our Black 95A material and is supplied with steel outer shells for better load distribution, offering improved durability and braking stability and a 140% increase over the worn rubber bush. Over the years we have seen a shift in the use of cars such as theBMW E92 M3 andE82 1M Coupe, with more of their time being spent on track and the power, chassis and braking modifications carried out, taking them from being quick road cars to very able and incredibly fast road-legal racers.Whilst creating this new part, we have revisited our existing non-adjustable partPFF5-401 Front Radius Arm to Chassis Bushso that it uses the same material, bush design and outer shell arrangement as above.This change in design increases stiffness by a further 25% over our previous offering for improved durability and braking stabilityand a 140% increase over the worn rubber bush.
