BMW 6 Series F06, F12, F13 (2011 - 2018) Front Radius Arm to Chassis Bush - PFF5-6101 This is a replacement part to replicate the geometry of the original part. For a caster offset version please use PFF5-6101G. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
