ST XA Coilover Kit for Select 2008-2017 Audi A4, A5, S4, and S5 - 18210075

Fits select 2008-2017 Audi A4, A5, S4, and S5 (B8/B8.5 chassis).

The ST XA Coilover Kit is engineered for drivers who want to influence more than just ride height. Featuring 16 distinct clicks of adjustable rebound damping, these coilovers allow you to precisely tune your Audi's driving behavior to achieve enhanced road control or improved ride comfort. Each kit is hand-built by KW in Germany and tested on shock dynos to ensure consistent performance and damping force before it leaves the factory.

Constructed with galvanized zinc-coated steel struts, the ST XA system is designed for long-term corrosion resistance. The ride height adjustment is managed via a friction-optimized polyamide composite spring perch with a stainless steel insert, preventing the oxidation and seizing common in all-metal designs. This ensures your height remains easily adjustable even after years of exposure to road debris and the elements.
