ST Coilover Kit 99-02 BMW Z3 M Coupe

This ST X Coilover kit gives you everything you need to lower and tune the suspension on your 1999-2002 BMW Z3 M Coupe. You get the complete set of four height-adjustable coilovers, each featuring a galvanized steel housing for corrosion resistance and an adjustable spring perch made from a durable, friction-optimized polyamide composite with a stainless steel insert. This composite material helps prevent oxidation between the strut and perch, ensuring the height adjustability remains functional over time. Each kit also includes elastomer bump stops with integrated dust protection systems to keep dirt and debris away from the piston rod and seals, helping to maintain the damper's performance and longevity.

These coilovers are designed to offer a sporty feel without sacrificing too much road comfort, making them a solid option for daily driving. The damping and spring rates are specifically tuned by ST's engineers in Germany to match the Z3 M Coupe's characteristics, providing an improved driving experience right out of the box. The height adjustability uses a unique trapezoidal thread pitch, making it straightforward to dial in your preferred ride height and achieve the look you want. Plus, the dampers themselves are built by hand at KW in Germany, with each unit tested on a dyno to ensure it meets performance standards before being boxed.

With this kit, you're getting a well-built suspension system that's application-specific for your Z3 M Coupe. The galvanized steel housing offers improved resistance to corrosion, and the integrated dust protection system on the bump stops helps keep the internal components clean. This kit comes with a 5-year limited warranty with unlimited mileage, and it's made in Germany.
