Adjustable Rear Anti-Roll Bar

The 034 Motorsport Adjustable Rear Anti-Roll Bar directly addresses the limitations of the stock rear suspension on the B6 and B7 generation Audi A4, S4, and RS4 models. The factory rear anti-roll bar is primarily tuned for comfort, resulting in significant body roll during spirited driving, pronounced understeer, and compromised corner-exit traction, particularly on Quattro models. By upgrading the rear bar, you can virtually eliminate body roll and significantly improve cornering grip and throttle lift-off behavior without sacrificing ride comfort. This anti-roll bar features a multi-position adjustment, allowing drivers to fine-tune the suspension behavior for various driving conditions, from daily road use to track day performance. The bar utilizes graphite-impregnated urethane silent blocks and high-strength machined aluminum mounting brackets for durability and performance. User feedback indicates that noise, vibration, and frequency transmission into the passenger compartment are negligible to low, ensuring a comfortable daily driving experience. Compatibility is confirmed for Audi A4 (B6/B7), S4 (B6/B7), and RS4 (B7) models, including both Quattro and Front-wheel drive (FWD) variants where applicable, across indicative years from 2001 to 2008. It is recommended to check your vehicle's VIN for precise compatibility, especially regarding specific engine or trim levels. Installation requires automotive mechanical skills, and professional installation at a workshop is recommended if you lack the necessary experience. It is advised to inspect and potentially replace the rear stabilizer bar links with the latest revision or adjustable spherical links, especially when using the bar in its firmest setting. Regular greasing of the bar bushings (approximately every six months) is recommended to prevent noise and ensure longevity.
