ST Coilover Kit 06-09 Pontiac Solstice / 07-09 Saturn Sky

The composite spring perch, made from wear-resistant polyamide with a stainless steel insert, is a key detail in how ST X Coilovers prevent corrosion between the strut and perch. This means you can adjust your ride height reliably for years to come, whether you're dialing in a lower stance for better cornering or just want to fine-tune your car's look. These coilovers are built by hand by the experts at KW in Germany, and each damper is tested on a shock dyno to ensure it's producing the correct forces before it's boxed up. This attention to detail means you get a well-built suspension system that’s application-specific for your Solstice or Sky.

ST X Coilovers offer a great balance for drivers who want improved handling without sacrificing too much comfort for daily driving. The dampers and spring rates are tuned by ST's vehicle dynamics engineers in Germany to perfectly match your specific car. You'll find the ride height adjustment is straightforward, thanks to the composite spring perch and a unique trapezoidal thread pitch. The galvanized steel housing on the struts also helps fight corrosion, extending the life of the components. Inside, a multi-layered sealing package, mono block guide system, and low-friction piston band work within the internal damper housing to keep things running smoothly and prevent dirt from damaging the hardened chrome piston rod.

This kit includes elastomer bump stops with integrated dust protection, which act as dynamic load limiters while helping to keep water and dirt away from the piston rod and seals. The result is a system that’s built to last and ready to improve your driving experience. You'll get a sporty feel and the ability to set your car's stance just how you like it.
