Audi A6 / S6 / RS6 A6 / S6 / RS6 C7 (2011 - 2018) Front Lower Radius Arm to Chassis Bush Caster Adjustable 75mm - PFF3-702GBLK This part suits arms with a 75mm diameter bush. For arms with 65mm bushes, please use PFF3-802GBLK. This is a replacement part that in our road series application is over 100% stiffer than the original rubber bush to withstand increased loading seen by this position on the car. PFF3-702GBLK provides +/- 0.5 caster offset that can be adjusted on the car 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 PFF3-702BLK. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
