Audi A4/S4 (B9) 17+

Riaction coilovers for the Audi A4 and S4 B9 chassis provide full control over ride height and damping, giving you the flexibility to fine-tune both stance and suspension response. Designed to keep the car stable under load, these performance shocks help reduce body movement while improving overall balance and composure.

On the road, the B9 platform feels tighter and more precise, with quicker response to steering inputs and stronger grip through corners. The suspension delivers a more refined yet controlled feel, making the car more engaging to drive while maintaining comfort and confidence in everyday conditions.
