Product Details

ST Suspensions is known for making well-built suspension components that offer a great balance of performance and value. This ST XA Coilover Kit is designed specifically for your 2008-2013 BMW 128i or 135i RWD convertible, giving you the ability to fine-tune both the ride height and the damping characteristics of your suspension. If you're looking to dial in the stance and handling of your E88 chassis, this kit puts that control directly in your hands.

What sets these coilovers apart is the attention to detail in their 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 body and the perch, ensuring that you can adjust your ride height smoothly for years to come. Each damper is built and tested by hand at KW in Germany, and they come preset to factory-recommended settings. You get 16 distinct clicks of adjustable rebound damping, allowing you to easily adjust how sporty or comfortable your car feels. The galvanized zinc-coated steel struts offer solid corrosion protection, and a built-in dust protection system keeps dirt and debris away from the piston rod and seals.

This kit includes everything you need to get your BMW sitting and handling just right. You'll find elastomer bump stops with integrated dust protection, a multi-layered sealing package, and a low-friction piston band inside the damper housing for smooth operation. With this ST XA Coilover Kit, you can achieve the precise driving dynamics you want without sacrificing ride comfort.
