Product Details
This Whiteline Rear Upper Inner Control Arm Bushing Kit fits the 2015-2020 Audi S3 (8V). Whiteline part number: W63578. Placement: rear. You receive 2 shell bushings, 2 tubes, 4 washers, an install guide, and grease.
A control arm bushing is the pivot where the arm joins the chassis or the wheel carrier. Factory rubber is chosen for quiet and comfort, so it squashes under braking, acceleration, and cornering and lets the arm move more than it should. A firmer replacement keeps the arm where it belongs, which steadies the alignment and gives the car a more consistent feel. Polyurethane resists deflection far better than the soft rubber it replaces.
Installation is rated moderate, with about 3 hours of work listed. Get the car aligned once it is back on the ground. To go with it on the Audi S3, see Adjustable Rear Sway Bar Link, Adjustable Rear Upper Control Arm Set, and Adjustable Front Sway Bar Link.
