Product Details

If you're looking to dial in the stance and handling of your 2009-2016 BMW Z4, this ST X Coilover kit is a solid option. It's built to give you that sporty feel when you're hugging curves, but it also keeps things comfortable for your daily drives. You get a wide range of height adjustability, so you can really dial in how your car looks and sits.

What sets these apart is the attention to detail in their construction. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This setup prevents corrosion between the strut and perch, meaning you can adjust your ride height for years to come without issues. The struts themselves are galvanized steel, offering good protection against rust, and they include a dust protection system to keep dirt and water away from the piston rod and seals. ST Suspensions relies on KW engineering for their dampers, ensuring a refined driving experience tailored specifically for your Z4.

These coilovers are assembled by hand by experts at KW in Germany, and each damper is tested to make sure it's performing correctly before it ships. You get a seamless ride height adjustment thanks to the composite spring perch and a well-designed trapezoidal thread. This kit is designed to be a direct fit for your Z4, giving you an improved look and feel on the road.
