Powerflex BMW F20 F22 F30 F32 Black Series Adjustable Front Radius Arm To Chassis Bush - Caster (PFF5-1901GBLK)
Unlock sharper steering, improved braking stability and more front-end grip with the Powerflex Black Series adjustable front radius arm to chassis bushes. Engineered in a 95 Shore Black Series polyurethane compound that is over 200% stiffer than the factory rubber, these bushes keep your BMW’s suspension geometry locked in under hard cornering and braking. PFF5-1901GBLK adds an on-car adjustable +/- 0.75 degrees caster offset to enhance steering feel and increase dynamic negative camber on turn-in for superior tyre contact and faster, more confident cornering on fast road and track.
At Nforcd we have fitted these to customer cars across the BMW F-series platform and feedback has been consistently positive - crisper turn-in, more consistent feedback and confidence-inspiring stability. If you drive your BMW hard, these are a serious upgrade over tired OE bushes.
