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

ST Suspensions is known for making well-built suspension components, and this ST XA Coilover Kit is a prime example of their focus on adjustability and performance. If you're looking to dial in the stance and handling of your 2018-2023 Audi A5 Sportback Quattro, this kit is designed to give you that control. It allows you to precisely set both the ride height and the rebound damping, so you can tailor the car's driving behavior to your exact preferences, whether you want a sportier feel or a more comfortable ride.

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 perch and the strut body, ensuring that you can adjust your ride height for years to come, while the stainless steel provides solid strength. ST builds these kits by hand at KW in Germany, and each damper is tested on a shock dyno before it ships out. You get 16 distinct clicks of rebound damping adjustment, controlled by a simple knob, allowing you to fine-tune how the suspension reacts to the road. The galvanized zinc-coated steel struts offer excellent corrosion protection, and an integrated dust protection system keeps dirt and debris away from the hardened chrome piston rod and internal valve packs.

This kit comes preset to factory-recommended damper settings, which are the same settings tested on KW's shock dynos. You'll also receive a detailed manual to help you understand the damper adjustments and reset them if needed. The elastomer bump stops include an integrated dust protection system, acting as dynamic load limiters while helping to maintain ride quality and durability. With this kit, you're getting a well-made suspension system that offers significant control over your vehicle's stance and handling.
