How do I adjust the ride height with these coilovers?

The ST X Coilover kit features a unique trapezoidal thread pitch on the spring perch. This design makes adjusting your vehicle's ride height straightforward, allowing you to dial in 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 long-lasting and easy height adjustability.

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.

About this part

Product Details

If you're looking to dial in the stance and handling of your 2006-2012 BMW E91 Sports Wagon or 2007-2013 E93 Convertible, the ST X Coilover kit is a solid option. This system lets you precisely adjust your vehicle's ride height, giving you control over both its look and how it hugs the road. It’s designed to offer a sporty feel without sacrificing the comfort you need for daily driving.

ST Suspensions builds these coilovers with a focus on durability and adjustability. The galvanized steel struts are treated to resist corrosion, and the spring perches are made from a tough, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the strut and perch, ensuring that you can easily adjust your ride height for years to come. Inside, you'll find hardened chrome piston rods protected by an integrated dust protection system, keeping dirt and debris away from the seals and valve packs. These dampers are tuned by ST's engineers in Germany, with KW providing the core damper technology, to match your specific BMW application for an improved driving experience.

This kit is built by hand at KW's facility in Germany, and each damper is tested on a dyno before it ships out. You get a seamless ride height adjustment thanks to the unique thread pitch on the spring perch. This kit comes with elastomer bump stops that also act as dust protection, helping to maintain ride quality and durability.
