How do I adjust the ride height with these coilovers?

The ST X coilovers use a unique trapezoidal thread pitch on the spring perch, which is made from a durable polyamide composite. This design makes adjusting the ride height straightforward, allowing you to dial in your preferred look.

What is the benefit of the composite spring perch?

The polyamide composite spring perch is designed to be wear-resistant and friction-optimized. It also prevents oxidation and corrosion between the strut and perch, ensuring that height adjustability remains functional over time.

Are these coilovers made in Germany?

Yes, the dampers are built by hand by experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify its performance before being included in the ST X coilover kit.

Product Details

Starting with a durable, friction-optimized polyamide composite spring perch with a stainless steel insert, the ST X Coilover system is built to last and make ride height adjustments straightforward. This composite material prevents corrosion between the strut and perch, ensuring that you can easily dial in your preferred look for years to come. These coilovers are designed for the everyday driver who wants improved handling without sacrificing too much road comfort.

The galvanized zinc-coated steel struts offer solid corrosion protection, and ST Suspensions includes 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, helping to maintain the damper's performance. Inside, a multi-layered sealing package, mono block guide system, and low-friction piston band work within the internal damper housing. All ST X coilovers are application-specific, tuned by vehicle dynamics engineers in Germany, and built by hand by KW in Germany, with each damper tested on a shock dyno before boxing.

This kit allows for seamless ride height adjustment, letting you fine-tune your tire and wheel fitment to achieve the stance you want. They offer a sporty feel that's still manageable for daily driving, making them a well-built option for enhancing your Mazda 3's performance and appearance.
