ST Coilover Kit 97-03 BMW 525i/528i/530i/540i E39 Sedan w/o Factory Air Suspension - ST X

ST Suspensions is known for providing well-built suspension components that offer a great balance of performance and value. For your 1997-2003 BMW 5 Series E39 sedan, the ST XA Coilover kit lets you dial in both the look and the driving feel of your car. This kit allows for a wide range of height adjustment, so you can achieve the stance you want, and it also gives you the ability to fine-tune the damping characteristics to match your driving style.

What sets this kit apart is the attention to detail in its construction and adjustability. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This design prevents corrosion between the strut and perch, ensuring that height adjustments remain easy over time, while the stainless steel provides solid strength. Each damper is tested by hand at KW in Germany before it ships, and the kit offers 16 distinct clicks of rebound damping adjustment. This means you can easily change how the car handles, whether you prefer a sportier feel or a more comfortable ride. The galvanized zinc-coated steel struts offer good corrosion protection, and an integrated dust protection system helps keep dirt and water away from the internal components, contributing to a long service life.

This kit is designed to give you precise control over your vehicle's driving dynamics. You'll receive a detailed manual to help you understand the damper settings, making it straightforward to reset them to factory recommendations or experiment with your own preferences. Everything you need to get started with adjustable ride height and damping is included in this kit.
