ST STX Adjustable Coilovers 07-09 Mazda 3 Speed

The ST X Coilover suspension starts with a spring perch made from a durable, friction-optimized polyamide composite with a stainless steel insert. This smart design prevents corrosion between the strut and perch, ensuring that you can easily adjust your ride height for years to come. These coilovers are built by hand by the experts at KW in Germany, with each damper tested on a shock dyno to verify it's making the proper forces before being boxed up. This attention to detail means you get a suspension that’s application-specific and perfectly tuned to match your Mazda 3 Speed’s dynamics.

You’ll appreciate the galvanized, zinc-coated steel struts that offer solid protection against corrosion, extending the life of the suspension. ST also incorporates an elastomer bump stop with an integrated dust protection system. This setup works to keep dirt and water away from the hardened chrome piston rod and valve packs, while also acting as a dynamic load limiter to maintain ride quality. The result is a suspension system that offers a sporty feel for hugging curves, but still provides a comfortable ride for everyday driving.

With ST X Coilovers, you get seamless ride height adjustment thanks to the composite spring perch and unique trapezoidal thread pitch. This makes it a breeze to dial in your preferred look and tire fitment. If you're looking to improve your driving experience with a well-built, application-specific coilover system, these are a solid option.
