Product Details

The ST X Coilover system starts with a spring perch made from a wear-resistant, friction-optimized polyamide composite. This material, paired with a stainless steel insert, is key because it prevents corrosion between the strut and perch. This means you can adjust your ride height seamlessly for years to come, without worrying about the threads seizing up. 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 gets boxed up.

These coilovers are designed to give you that sporty feel you're looking for, while still keeping things comfortable for daily driving. The dampers and spring rates are specifically tuned by ST's vehicle dynamics engineers in Germany to match your Infiniti G37 Coupe perfectly. You get a wide range of height adjustability, so you can dial in the exact look you want for your car, whether you're aiming for a subtle drop or something more aggressive. The galvanized steel housing on the struts also helps fight off corrosion, keeping them looking good and working right.

Included with the kit is an elastomer bump stop with an integrated dust protection system. This helps keep dirt and water away from the piston rod and seals, extending the life of the damper. You'll also get a 5-year limited warranty with unlimited mileage, underscoring the confidence ST Suspensions has in their German-made product.
