ST Coilover Kit 06-12 BMW E91 Sports Wagon X-Drive AWD (6 Cyl)

ST Suspensions is known for providing well-built suspension components that offer a noticeable improvement in handling without sacrificing too much comfort. This ST X Coilover kit is specifically designed for your 2006-2012 BMW E91 Sports Wagon with xDrive AWD and a 6-cylinder engine, including the 325xi, 328xi, and 328i xDrive models. It’s built to give you that sporty feel you’re looking for, letting you hug those curves with confidence while still keeping the ride comfortable enough for daily driving.

What sets these coilovers apart is the attention to detail in their construction and adjustability. The galvanized steel struts are treated to resist corrosion, ensuring they hold up over time. You get a composite spring perch made from a durable, friction-optimized polyamide with a stainless steel insert. This combination prevents corrosion between the strut and perch, making height adjustments smooth and reliable for the life of the kit. Plus, ST Suspensions relies on world-class engineering from KW for their dampers, and each unit is tested by hand in Germany to make sure it performs exactly as it should. You can easily adjust the ride height using the unique trapezoidal thread pitch, allowing you to dial in your preferred look and stance.

To keep everything running smoothly, these coilovers include an elastomer bump stop with an integrated dust protection system. This setup prevents dirt and moisture from reaching the hardened chrome piston rod and seals, protecting the internal components. The internal damper housing features a multi-layered sealing package, a mono block guide system, and a low-friction piston band for consistent performance. This kit is application-specific for your BMW, meaning the dampers and spring rates are tuned to perfectly match your vehicle's weight and dynamics, offering a sporty yet simple setup that’s ready for everyday use.
