What is the main benefit of the composite spring perch?

The composite spring perch is made from a wear-resistant, friction-optimized polyamide composite with a stainless steel insert. This design prevents oxidation between the strut and perch, ensuring that height adjustments remain easy to make over time and corrosion is prevented.

Are these coilovers adjustable for damping force?

The ST X Coilover system is designed for preset damping, meaning the damping force is fixed and tuned by ST engineers in Germany to match the specific vehicle application for a balance of sporty performance and road comfort. Further damping adjustments are not a feature of this specific model.

What is included in the ST X Coilover kit?

The kit includes a complete set of four coilovers, each featuring a galvanized steel housing and a composite spring perch with a stainless steel insert. It also includes elastomer bump stops with integrated dust protection systems to help maintain the longevity of the internal components.
