Powerflex Front Radius Arm To Chassis Bushes Caster Adjustable – BMW 1 Series F20 F21 – Part No. PFF5-1901G
Unlock sharper steering, improved stability and better tyre contact with Powerflex Front Radius Arm To Chassis Bushes for the BMW 1 Series F20 and F21. The PFF5-1901G Road Series bush is 60% stiffer than the original rubber bush to control unwanted suspension flex under braking and cornering. With on-car caster adjustment of +/- 0.75, you can fine tune steering feel and straight-line stability, while additional caster generates more negative camber on turn for increased front-end grip during hard cornering.
We have fitted and used these bushes ourselves and the feedback is consistently positive. Customers report a noticeable improvement in steering precision, consistency and confidence on both road and fast road drives. If you want a direct-fit upgrade that transforms the front end of your BMW 1 Series, this is it.
