ST Coilover Kit 06-11 Honda Civic/Civic SI

If you're looking to give your 2006-2011 Honda Civic or Civic Si a more aggressive stance and improved handling, this ST X Coilover kit is a solid option. It's designed to give you that sporty feel for hugging curves while still keeping things comfortable for daily driving. You get a wide range of height adjustability, so you can dial in the perfect look for your car, whether you want a subtle drop or something more dramatic.

What sets these apart is how they're built. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the strut and perch, ensuring that you can adjust your ride height smoothly for years to come. The steel struts themselves are galvanized for extra protection against rust, and they include a dust protection system to keep dirt and debris away from the hardened chrome piston rod and internal valve components. Inside, you'll find a multi-layered sealing package, a mono block guide system, and a low-friction piston band, all working within a pressure-resistant internal damper housing. ST Suspensions relies on KW for their damper engineering, which means you're getting a well-tuned setup specifically for your Civic that improves the driving experience.

These coilovers are built by hand by the experts at KW in Germany, and each damper is tested on a shock dyno before it's boxed up. The dampers and spring rates are pre-tuned by ST's vehicle dynamics engineers in Germany to perfectly match your specific Civic application, offering a great balance of sporty performance and everyday drivability. You'll find the ride height adjustment straightforward thanks to the composite spring perch and the unique trapezoidal thread pitch.
