ST XTA Plus 3 Coilover Kit Audi A3/S3/RS3 (8V) Quattro

ST Suspensions is known for providing well-built suspension components that offer a significant upgrade over stock. This XTA Plus 3 coilover kit is their most versatile offering, designed to give your Audi A3, S3, or RS3 Quattro the tools you need for maximum performance on the road and the track. It allows for precise adjustments to fine-tune your car's handling characteristics, whether you're setting it up for spirited driving or track days.

At the heart of this kit are KW dampers, built by KW in Germany, which are adjustable in 24 clicks for both high-speed and low-speed compression, and 18 clicks for rebound damping. This level of adjustability means you can dial in your suspension to match your driving style and any modifications you might have, like a roll cage or different wheel loads. The kit also features linear race springs for consistent response and aluminum unibal top mounts that improve steering feedback and allow for camber adjustments. Ride height is easily adjusted via a seamless thread on the galvanized strut housing, even with the kit installed, letting you set your preferred stance.

The construction emphasizes longevity and performance. The galvanized steel housing resists corrosion, and the elastomer bump stops with integrated dust protection keep dirt and water away from the piston rod and seals. The composite spring perches are made from a wear-resistant, friction-optimized polyamide with a stainless-steel insert, preventing oxidation and maximizing strength. Each damper is tested on a shock dyno before being boxed, ensuring it meets proper force specifications. This kit includes a parts approval certificate and is backed by a 5-year limited warranty with unlimited mileage.
