ST Coilover Kit 03-08 BMW Z4 (Z85)

ST Suspensions is known for providing well-built suspension components, and this ST X Coilover kit for your 2003-2008 BMW Z4 is no exception. If you're looking to dial in your car's stance and improve its handling without sacrificing too much ride comfort, this kit is a solid option. It's designed to give you that sporty feel you want for spirited driving while still being comfortable enough for your daily commute.

What sets these coilovers apart is the attention to detail in their construction and adjustability. You get a wide range of height adjustment thanks to the composite spring perch, which is made from a durable, friction-optimized polyamide with a stainless steel insert. This design helps prevent corrosion between the strut and perch, ensuring that you can adjust your ride height smoothly for years to come. The galvanized steel struts offer good protection against corrosion, and ST includes an elastomer bump stop with an integrated dust protection system to keep dirt and water away from the piston rod and seals. These dampers are tuned in Germany by KW, a well-known name in performance suspension, to match your specific Z4 application.

This kit is built by hand by experts at KW in Germany, and each damper is tested on a dyno before it's boxed up. You'll get a seamless ride height adjustment process, allowing you to achieve your desired look and tire fitment. It's a complete kit designed for your specific vehicle, offering a great blend of performance and everyday usability.
