CTS Turbo B9/B9.5 Audi A4/S4/A5/S5/RS5/Allroad Rear Sway Bar Upgrade

The CTS Turbo rear sway bar upgrade replaces the factory B9/B9.5 Audi component with a precision-engineered solution designed to limit body roll during aggressive cornering and lane changes. Developed specifically for A4, S4, A5, S5, RS5 and Allroad variants from 2017 onwards, this upgrade works by increasing rear axle stiffness to improve chassis balance and steering feedback. Adjustable end links allow tuning to suit track work or spirited road driving. Built from high-grade materials with polyurethane bushings for consistent performance and durability under Australian conditions.
