Product Details

These ST Suspensions ST X coilovers, with factory air suspension, fit the 1999-2003 BMW 5 Series Sports Wagon (E39).

The ST X Coilover Suspension for the E39 5 Series Sports is built for daily driving, with sharper cornering and road comfort. ST X Coilover Kits have precise ride height adjustment. We manufacture an adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability. Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs.

We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing. ST dampers are engineered by KW. Every ST X Coilover Kit is application specific and made for daily driving.

Improved driving dynamics and handling

Designed in conjunction with KW Suspension Germany, ST X Coilover Kit deliver a sporty handling by reducing the bodyroll during compression as well as improving agility when driving fast. The high-quality production of each ST X coilover includes a low-friction and pressure resistant housing alongside a chrome-plated piston rod for maximum longevity. A mono block guide and ST seal package ensures the twin-tube dampers remain free of dirt particles in all weather conditions.
