BMW E9X 3 Series / E8X 1 Series Front Tension Arm Bushing Set - Adjustable

PFF5-401G Front Radius to Chassis Bush Caster Adjustable to provide up to +/- 0.75 degrees of on-car caster adjustment, resulting in greater in-corner camber gain, improved stability at high-speed and the ultimate optimisation of your vehicle's front wheel geometry. Made in our stiffest Black 95A material and supplied with steel outer shells for better load distribution and an offset adjustable CNC-machined stainless-steel sleeve and spanner, it combines all of the necessary ingredients to be perfectly suited to both road and track use.
