Overview

If you're looking to improve the handling of your Audi B8 A4/S4/RS4/A5/S5/RS5, this is the best place to start! These cars have a lot more body roll than what's to be desired factory, and the stock sway bars don't quite do enough to keep the body from understeering.

TGK Motorsport Sway bars are made from solid spring steel to give you the best strength in a smaller size, while helping eliminate understeer from this platform.

Frequently Asked Questions
Which stiffness setting should I choose — Stiff or Stiffer?
The Stiff setting is recommended for street-driven vehicles or those wanting a noticeable improvement over stock without an overly aggressive feel. The Stiffer setting is best suited for track use or drivers who want maximum roll reduction and the sharpest possible handling response.
Can I install the front and rear sway bars independently, or do I need to purchase both?
Each bar is available independently, so you can install just the front or just the rear based on your specific handling goals. However, installing both together provides the most balanced and complete improvement to the platform's body roll and understeer characteristics.
Do these sway bars require any modification to the vehicle for installation?
The front sway bar bushings utilize the OEM mounting locations, so no modification is required for the front. The rear bar installs using the included 6061-T6 billet brackets, which are designed to bolt into the factory positions on the B8 chassis.
What is the check valve grease port on the rear brackets used for?
The check valve grease port allows you to re-grease the rear bar's bushing interface over time without disassembling the brackets. This extends the service life of the bushings and keeps the bar operating quietly and smoothly.
Are these sway bars compatible with all variants of the B8 platform including RS4 and RS5?
Yes. These sway bars are designed to fit the 2008–2016 Audi A4, 2008–2016 S4, 2012–2015 RS4, 2007–2016 A5, 2007–2016 S5, and 2010–2016 RS5, covering the full B8 and B8.5 model range across all trim levels.
