034Motorsport is proud to offer the ultimate rear sway bar upgrade for the B6/B7 Audi A4/S4/RS4! The 034Motorsport Adjustable Solid Rear Sway Bar is made from high-quality spring steel for maximum rigidity, and is designed to combat understeer while reducing body roll under hard cornering. Engineered to be used effectively with the stock front sway bar, the 034Motorsport Adjustable Solid Rear Sway Bar substantially reduces body roll while greatly improving turn in and off throttle oversteer, without compromising comfort on the street.
We highly recommend using this upgrade in conjunction with Spherical Rear Sway Bar End Links
for maximum performance.
