ST 2017+ Audi A5 (B9) Sportback Quattro XA Height & Rebound Adjustable Coilover Kit 0.4in-1.4in

This ST XA Coilover Kit includes four complete coilover assemblies, each featuring a galvanized zinc coated steel strut housing with an integrated dust protection system. You also get composite spring perches made from a durable, friction-optimized polyamide with a stainless steel insert, designed to prevent corrosion and ensure long-lasting adjustability. The kit comes with elastomer bump stops that have an integrated dust protection system to keep dirt and water away from the piston rod and seals. Each damper is tested on a shock dyno before packaging, and a detailed damper setup manual is included to guide you through adjusting the ride behavior.

These coilovers allow you to adjust both the ride height and the rebound damping. The ride height can be lowered between 0.4 and 1.4 inches, giving you the flexibility to achieve your desired stance. The rebound damping can be adjusted across 16 distinct clicks using a simple knob, letting you fine-tune how the car handles from comfortable to sporty. The spring perches are constructed from a wear-resistant polyamide composite with a stainless steel insert, which prevents oxidation between the strut and perch while providing strength. The galvanized steel housing offers improved resistance to corrosion, and the internal damper components are protected by a multi-layered sealing package, a mono block guide system, and a low-friction piston band.

ST XA Coilovers are built by hand by experts at KW in Germany. Each damper is tested on a shock dyno to ensure it meets proper force specifications before being boxed. This attention to detail means you get a well-built suspension system that’s ready to perform. The composite spring perch and unique trapezoidal thread pitch make ride height adjustments straightforward, allowing you to dial in your preferred look and stance. With adjustable rebound damping, you have direct control over how comfortable or sporty your car feels, making it easy to set up the suspension for your driving style.
