034 Motorsport – Dynamic+ Adjustable Rear Sway Bar
For Audi B9/B9.5 A4, S4, A5, S5, RS5, Allroad
Unlock sharper, more responsive handling in your Audi B9 with the 034Motorsport Dynamic+ Adjustable Rear Sway Bar. Engineered from a single piece of 22.2mm solid spring steel, this bar dramatically reduces body roll, improves turn-in, and corrects the factory understeer bias—without compromising everyday comfort.
This product was thoroughly tested on the street and track using 034Motorsport’s in-house B9 Audi A4 development vehicle. The result is a sway bar that delivers significantly reduced understeer, improved rotation, and enhanced mid-corner stability, all while retaining OEM levels of drivability.
Designed specifically to work with the factory front sway bar, this upgrade alone transforms the handling balance of the B9 chassis. A stiffer front bar is not required. In fact, upgrading the front bar can worsen understeer characteristics. With the stock front bar and the 034 Dynamic+ rear bar, body roll is reduced substantially while turn-in response and off-throttle rotation are dramatically improved.
