034 Motorsport is proud to offer the ultimate sway bar upgrade package for the B9 Audi A4/S4, A5/S5, and Allroad! The 034Motorsport Dynamic+ Sway Bar Kit features perfectly-matched front and rear sway bars made from high-quality spring steel for maximum rigidity and durability.

Designed to reduce body roll and enhance steering feel further than a rear sway bar upgrade alone, 034 Motorsport's Dynamic+ Sway Bar Kit is the ideal upgrade for those in search of confidence-inspiring handling on track.  Unlike the 22.2mm Dynamic+ Rear Sway Bar, installing the Dynamic+ Sway Bar Kit will result in a noticeably firmer ride.  As such, we recommend this product for those who are looking for a more significant shift in suspension dynamics from comfort to performance.

The Dynamic+ Sway Bar Kit was thoroughly evaluated on the street and track with the 034 Motorsport B9 Audi A4 and 034Motorsport B9 Audi S4 before release.
