H&R 99-03 BMW M5 E39 RSS Coil Over

For all those who want to influence more than just their ride height. ST XA Coilovers deliver the look you need through a wide range of height adjustment. With an extensively adjustable damper setup, you can precisely adjust the driving behavior of your car to achieve enhanced road control without a compromise in comfort. ST XA Coilover kits deliver precise adjustment to your ride height and look of your car. We manufacture the 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 while the stainless steel insert provides strength and confidence! ST XA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 16 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, sportiness, or something in between; ST XA puts the finer details of the driving dynamics in your hands. 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 XA Coilovers deliver the look you need through a wide range of height & damping adjustment. Precisely adjust the driving behavior of your car to achieve enhanced road control without compromising comfort.
ST Coilover Kits enable you to individually adjust the ride height of your car to improve the appearance and driving behavior. Depending on your selection, ST coilover kits offer a wide range of adjustments giving you the tools needed to dial them into your requirements.

• Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
• Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
• ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it’s making the proper forces before being put into the ST box.
• Seamless Ride Height Adjustment – ST’s composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look
• ST XA coilovers feature adjustable rebound damping which puts you in control of how comfortable or sporty your car feels.
• Zinc galvanized steel housing for improved resistance to corrosion.
• 5 Year Limited Warranty – Unlimited Mileage
• Made in Germany

KW V2 INOX-LINE coilovers are the perfect solution for drivers who want more than just outstanding looks and adjustable ride height. In addition to stainless steel coilover struts, and corrosion-resistant components built for long term durability, KW V2 coilovers utilize TVR-A (Twin Valve Rebound – Adjustable) technology that allow Adjustment of the rebound damping characteristics with 16 clicks so you can fine tune the ride comfort or performance to your satisfaction. As with all KW coilovers our engineers develop vehicle specific damper settings that undergo comprehensive testing on the Nurburgring Nordschleife and in our KW 7-post Driving Dynamic Test Center. With a KW coilover kit the driving experience is more dynamic and direct. With the rebound adjustability you have a more direct influence on the handling or comfort of the car. With 16 precise clicks you can adjust the KW dampers (more firm or more comfortable) without affecting the compression damping fine-tuned by our engineers. The two-stage, patented TVR-A (Twin Valve Rebound – Adjustable) technology enables a small volume of oil flow through an adjustable, conically shaped, low-speed bypass during low damper speeds, while at high damper speeds, the main rebound stage valve opens allowing a larger volume of oil to flow. This provides a big improvement in terms of ride comfort without influencing the high-speed range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control. With KW V2 coilovers you can achieve maximum lowering within an approv ed lowering range that ensures a proper functioning suspension and adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar.
For sporty drivers who want more than just outstanding looks and lowering within the tested Adjustment -angle, the KW V2 “INOX-LINE” coilovers are the perfect suspension featuring TVR-A adjustable rebound damping technology.
For over 20 years, KW automotive has been the market leader and driving innovation as a manufacturer of individual suspension solutions for the road and in all types of motorsports.
