Audi A6 / S6 / RS6 A6 / S6 / RS6 C7 (2011 - 2018) Front Lower Radius Arm to Chassis Bush 75mm - PFF3-702 This part suits arms with a 75mm diameter bush. For arms with 65mm bushes, please use PFF3-802. This is a replacement part that in our road series application is 35% stiffer than the original rubber bush to withstand increased loading seen by this position on the car. For a caster adjustable option, please use PFF3-702G. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
