ST X Coilover Kit Audi A5 (B9) Sportback Quattro

ST Suspensions is known for making well-built suspension components that improve a car's handling without sacrificing too much comfort. This ST X Coilover kit for your 2018-2023 Audi A5 Sportback Quattro is a prime example, offering a great balance for drivers who want a sportier feel and the ability to dial in their car's stance. It's designed to hug curves better while still providing a comfortable ride for daily driving.

What sets these coilovers apart is the attention to detail in their construction and adjustability. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the strut and perch, ensuring that you can adjust your ride height smoothly for years to come. The galvanized zinc-coated steel struts offer solid protection against rust, and a built-in dust protection system keeps dirt and debris away from the hardened chrome piston rod and internal seals. ST Suspensions relies on engineering from KW, a well-known name in performance suspension, to tune the dampers and spring rates specifically for your A5 Sportback, ensuring a perfect match for everyday driving and spirited runs.

You get seamless ride height adjustment thanks to the composite spring perch and a unique trapezoidal thread pitch, making it easy to achieve your desired look. These coilovers are built by hand by experts at KW in Germany, and each damper is tested on a shock dyno before it ships. This kit includes elastomer bump stops with integrated dust protection, which act as dynamic load limiters while helping maintain ride quality. You'll also benefit from a 5-year limited warranty with unlimited mileage, reflecting the confidence ST Suspensions has in their German-made product.
