For those looking for the next step in improved handling, we are pleased to release our rear sway bar upgrade for the Audi S4 / S5 (B9). Intended to be paired with our lowering spring kit, the rear sway bar upgrade will dramatically reduce body roll to create a more neutral steering balance. This sway bar upgrade is specifically designed to function with the OEM front sway bar, getting rid of the factory under-steer while allowing enough compliance for a comfortable ride and predictable suspension behavior.

What's included:

Sway Bar - The sway bar is a 22.2mm solid bar that is manufactured in the USA from high quality spring steel. We opted for a solid design, as it ensures that our sway bar will last a lifetime of abuse without risk of breakage or deformation. In order to maintain the factory suspension geometry (for those using stock end links), we opted for a non-adjustable design.

Billet Brackets - Included with each sway bar is a set of our custom billet brackets. Through CAD design and stress analysis, we developed a stronger alternative to typical stamped brackets. Each bracket is CNC machined, anodized black and finished with a stealth "e".

Steel Subplates - The factory sway bar bushings sit inside a void on the rear subframe. In order to properly utilize our provided bushings, we include a steel subplate which serves as a base for our bushings. By using our included subplate, the subframe can properly accept our included D-shaped bushing.

Bolts - Our included alloy steel bolts offer increased strength over their factory counter parts, and are slightly longer to accommodate our bracket and subplates. They utilize a flange head to evenly disperse load without the need for a washer, similar to the factory bolt.

Upgraded Bushings - The included bushings are designed to minimize noise typically associated with polyurethane bushings. Using a unique interior groove, the bushing is able to better hold and maintain lubricating grease. This ensures continued usage without developing squeaks and creaks.
