The CTS Turbo B9/B9.5 Audi A4/S4/A5/S5/RS5/Allroad Rear Sway Bar is designed to bring precise handling and enhanced stability to the B9 platform. Featuring a 2-way adjustable design, it allows drivers to fine-tune their vehicle’s handling, with an increased sway bar rate of 175% to 214% over the factory hollow rear sway bar. The one-piece, 22mm diameter solid construction ensures superior durability and rigidity, dramatically reducing body roll for a flatter, more controlled feel through corners.
With this sway bar, drivers will experience sharper turn-in response and enhanced rear-end stability, delivering smoother and more predictable cornering. Made from high-quality materials for consistent performance, this sway bar is ideal for those who want a responsive, confidence-inspiring setup on both street and track, providing a dynamic improvement in handling without sacrificing daily driving comfort.
Features:
- 2-Way Adjustable: Allows for fine-tuning of sway bar stiffness, with options for 175% to 214% increased sway bar rate over the factory “Sport” sway bar, providing flexibility based on driving style and conditions.
- Solid One-Piece Construction: Built from a 22.5mm diameter solid steel bar for enhanced durability and strength, delivering consistent performance under high-stress driving conditions.
- Reduced Body Roll: Helps keep the car flat and balanced during aggressive cornering, resulting in sharper handling and better road-holding capabilities.
- Enhanced Steering Response: Provides a more direct and responsive steering feel, ideal for drivers seeking a precise and confident driving experience.
