034Motorsport Dynamic+ Sway Bar Kit, B9/B9.5 Audi A4/S4, A5/S5/RS5, Allroad
034Motorsport is proud to offer the ultimate sway bar upgrade package for the B9/B9.5 Audi A4/S4, A5/S5/RS5, 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 further reduce body roll and enhance steering feel than a rear sway bar upgrade alone, 034Motorsport's Dynamic+ Sway Bar Kit is the ideal upgrade for those in search of confidence-inspiring handling on the street and track.
Please Note: We highly recommend using this upgrade in conjunction with Spherical Rear Sway Bar End Links and Spherical Front Sway Bar End Links for maximum performance. Unlike the Dynamic+ Rear Sway Bar, installing this sway bar kit will result in a noticeably firmer ride.
NVH Levels: NONE - LOW
NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. 034Motorsport Sway Bars transfer none to low amounts of NVH to the cabin based on user feedback. 034Motorsport Sway Bar Bushings should be lubricated on average every ~6 months for safe upkeep, or if you hear the bushings start to make any noise. NVH is subjective so some users may find NVH to be increased or decreased from our rating.
