Audi B9 S4/S5 EMD Auto eMMOTION 22.2mm Rear Sway Bar
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.

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.
