034Motorsport is proud to offer the ultimate rear sway bar upgrade for the B5 Audi A4/S4/RS4 Quattro! 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.

This product was tested thoroughly on the street and track on our shop B5 Audi S4 before release.  The 034Motorsport Adjustable Solid Rear Sway Bar substantially reduces understeer and body roll on B5 Audi A4/S4/RS4 Quattro vehicles without compromising comfort on the street.

In addition, the 034Motorsport B5 Audi A4/S4/RS4 Quattro Rear Sway Bar is engineered to be used effectively with the stock front sway bar.  No upgrade in the front is needed or required.  The addition of a stiffer front bar introduces even more push, requiring an even bigger bar in the back.  With the stock front sway bar and upgraded 034Motorsport Solid Rear Sway Bar, body roll is virtually eliminated while turn in and off throttle oversteer are greatly improved.

Please Note: For lowered vehicles, always check all clearances over the full articulation of the suspension in order to identify possible interference. We recommend running 034Motorsport suspension components, as they have been designed and tested to work together, without interference.
