034Motorsport is proud to offer the ultimate rear sway bar upgrade for the B8/B8.5 Audi A4/S4/RS4 and A5/S5/RS5! The 034Motorsport Adjustable Solid Rear Sway Bar is made from a single piece of high-quality, 25.4mm thick 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 B8 Audi S4 3.0 TFSI before release. The 034Motorsport Adjustable Solid Rear Sway Bar substantially reduces understeer and body roll on B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5 vehicles without compromising comfort on the street.
In addition, the 034Motorsport B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5 Rear Sway Bar is engineered to be used effectively with the stock front sway bar. No upgrade in the front is required. The addition of a stiffer front bar can positively affect turn-in feel, but ultimately worsens the platform's tendency to understeer. 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: We recommend upgrading to our Spherical B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 Rear Sway Bar End Links to attain the maximum performance benefit when installing this rear sway bar upgrade.
