What is the primary benefit of the composite spring perch?

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

How is ride height adjusted with these coilovers?

Ride height is adjusted using the composite spring perch and a unique trapezoidal thread pitch. This system makes adjusting your vehicle's stance straightforward, allowing you to dial in your preferred look and tire fitment.

Are these coilovers designed for comfort as well as performance?

Yes, the ST X coilovers are designed to offer an ideal mix of sporty handling and everyday comfort. The dampers and spring rates are specifically tuned by engineers in Germany to match your vehicle's application, providing a balanced driving experience.
