What is the primary benefit of the composite spring perch?

The composite spring perch is made from a wear-resistant, friction-optimized polyamide with a stainless steel insert. This design prevents oxidation between the strut and perch, which stops corrosion and ensures the height adjustability remains functional over time.

How is the ride height adjusted with these coilovers?

Ride height adjustment is made easy thanks to ST's composite spring perch and a unique trapezoidal thread pitch on the strut body. This allows you to precisely dial in your preferred ride height and vehicle stance.

Are these coilovers made in Germany?

Yes, the ST X coilovers are built by hand by experts at KW Suspensions in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it meets proper force specifications before being packaged.

Product Details

Starting with a durable, galvanized steel housing for improved resistance to corrosion, the ST X Coilover system is built to last. This kit is specifically tuned by ST's vehicle dynamics engineers in Germany to match your 2015-2020 Audi A3, offering a sporty feel without sacrificing everyday road comfort. The adjustable spring perch is made from a wear-resistant, friction-optimized polyamide composite with a stainless steel insert, preventing oxidation and ensuring long-lasting, easy height adjustability. This design choice is key to preventing corrosion between the strut and perch, a common issue that can seize up other systems.

These coilovers feature an elastomer bump stop with an integrated dust protection system. This setup works to keep dirt and water away from the hardened chrome piston rod and seals, while the bump stops themselves act as dynamic load limiters to maintain ride quality and durability. The internal damper housing is reinforced with a multi-layered pressure-resistant sealing package, a mono block guide system, and a low-friction piston band, all contributing to a smooth and reliable performance. Each damper is built by hand by the experts at KW in Germany and tested on a shock dyno before being boxed, ensuring they meet proper force specifications.

With a wide range of height adjustability, you can easily dial in your preferred look and tire fitment. The ST X coilovers are designed to be application-specific for your Audi A3, providing an improved driving experience that balances performance and practicality.
