Hotchkis Sport Suspension 22827 Sport Sway Bar Set. Although the Audi RS6 is undoubtedly an excellent handing car right out of the box RS6 owners have requested Hotchkis Sport Suspension to address the slight roll issue most notably at mid-corner. Hotchkis now offers a RS6-specific sway bar set meaning this set fits the slight design changes inherent in the RS6. Because of its super car status the RS6 differs from the standard A6 especially at the rear end. Hotchkis' sway bar set is designed to clear componentry on the RS6 and operate freely and efficiently. This set includes a 35mm tubular front bar and a 24mm tubular rear bar. In addition the set includes all necessary mounting hardware and easy-to-read instructions. No cutting welding or modifying in any way. RS6 drivers who have tried the Hotchkis sway bars are surprised at the reduction of roll without sacrificing ride quality. Very important when the RS6 comes from the factory with aggressive spring rates and shock valving. In comparison the rear bar from the factory on the RS6 is a stout 20mm solid bar but even the weight of the car overrides this bar during spirited driving. Specifications: Front 35mm Tubular Non-Adjustable Stiffness: +50% (Compared to stock RS6). Rear 24mm Tubular 2 Position Adjustable Stiffness: +49% +67% (Compared to stock RS6)
