Product Details
This Whiteline Rear Upper Outer Control Arm Bushing fits the 2015-2020 Audi S3 Premium Plus, Prestige (8V). Whiteline part number: W63579. This part is for the rear of the vehicle. The kit contains 2 shell bushings and 2 tubes.
Every time the wheel moves, the control arm swings on its bushings. When they are soft or worn, the arm shifts under load, the alignment changes as the car moves, and steering and braking feel less precise. A stiffer bushing cuts that unwanted movement while still letting the arm pivot freely. The polyurethane used here deflects much less than the original rubber under the same load.
Expect a moderate job of about 3 hours. An alignment is required after installation. Other Whiteline parts we list for the Audi S3: Adjustable Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Front and Rear Sway Bar Kit.
Features
- Install guide: An install guide comes in the box.
- Bushing compound: The bushing material stands up to oil, grease, ozone, and weather.
- Bonded design: The bushing is bonded for strength where loads are highest.
- Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
- Corrosion protection: The hardware is plated to stand up to road conditions.
- Material: Made from polyurethane.
