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 set your preferred look and stance.

What is the benefit of the composite spring perch?

The spring perch is made from a durable, friction-optimized polyamide composite with a stainless steel insert. This material combination prevents corrosion between the strut and perch, ensuring that height adjustability remains functional 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 to verify it's making the proper forces before being packaged.

The steel struts themselves are galvanized for extra protection against rust. ST also includes a dust protection system that keeps dirt and water away from the piston rod and seals, plus a multi-layered sealing package inside the damper for smooth operation. These dampers are even built by KW, a well-respected name in suspension engineering, ensuring a solid performance upgrade tailored specifically for your Mazdaspeed 3.

This kit is built by hand in Germany and each damper is tested before it ships out. You'll be able to dial in your preferred ride height to get that perfect stance and fitment for your wheels. It’s a complete package designed to improve your driving experience.
