034 Motorsport Dynamic+ Adjustable Rear Sway Bar | Audi B9 / B9.5 A4 | S4 | A5 | S5 | Allroad | 034-402-1010

034Motorsport is proud to offer the ultimate rear sway bar upgrade for the B9 Audi A4/S4, A5/S5, and Allroad! The 034Motorsport Dynamic+ Adjustable Rear Sway Bar is made from a single piece of high-quality, 22.2mm 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 034Motorsport's in-house B9 Audi A4 Development Vehicle before release. The 034Motorsport Dynamic+ Adjustable Rear Sway Bar substantially reduces understeer and body roll on B9 Audi A4/S4, A5/S5, and Allroad vehicles without compromising comfort on the street.

In addition, the 034Motorsport Dynamic+ Rear Sway Bar is engineered to be used effectively with the stock front sway bar, and maintains factory levels of comfort and driveability. No upgrade in the front is required with this rear sway bar. 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 substantially reduced, while turn in and off throttle oversteer are greatly improved.
