How do I adjust the ride height with these coilovers?

The ST X coilovers feature a composite spring perch with a unique trapezoidal thread pitch. This design makes adjusting the ride height straightforward, allowing you to easily dial in your preferred stance for your vehicle.

What is the benefit of the composite spring perch and stainless steel insert?

The polyamide composite material is wear-resistant and friction-optimized, while the stainless steel insert maximizes strength. This combination prevents oxidation and corrosion between the strut and perch, ensuring smooth and reliable height adjustment over time.

Are these coilovers made in Germany?

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