BMW 5 Series F10, F11 (2010 - 2017) Front Radius Arm to Chassis Bush Caster Adjustable - PFF5-6201G This is a replacement part that uses our Black Series material to boost stiffness over the original part by 18% to withstand increased loading seen by this position on the car. PFF5-6201G provides 6mm offset to provide +/- 0.5 caster adjustability for improved steering feel. Additional caster will also create additional negative camber on turn giving improved tyre contact with the road under heavy cornering. For a non-adjustable version of this bush please use PFF5-6201. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
