ST X Height & Rebound Adjustable Coilover Kit - 2017+ Audi A5 (B9) Sportback Quattro

This is the ST X Coilover kit for your 2018-2023 Audi A5 Sportback Quattro. It's designed to give you that sporty feel when you're taking corners, but without sacrificing too much comfort for daily driving. You get a wide range of height adjustment, so you can really dial in the look of your car, making it sit just right.

What makes these stand out is how they're built. The spring perches are made from a tough, friction-optimized polyamide composite with a stainless steel insert. This setup prevents corrosion between the strut and the perch, meaning you can adjust the ride height for years to come without it seizing up. The steel struts themselves are galvanized for extra protection against rust. Plus, they've got a dust protection system that keeps dirt and water away from the piston rod and seals, and a multi-layered sealing package inside the damper housing to keep things running smoothly. ST Suspensions uses damper technology from KW, a well-known name in performance suspension, to ensure a great driving experience tailored specifically for your A5 Sportback.

These coilovers are built by hand by experts at KW in Germany, and each damper is tested on a dyno before it ships out. You get a seamless ride height adjustment thanks to the composite spring perch and a unique trapezoidal thread. They're built to last and come with a 5-year limited warranty with unlimited mileage.
