How do I adjust the ride height with these coilovers?

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

What is the 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 combination prevents corrosion between the perch and the strut body, ensuring long-lasting and smooth height adjustability.

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 to verify it meets proper force specifications before being packaged.
