ST XA Coilover Kit 06-12 BMW E91 Sports Wagon (RWD) / 07-13 BMW E93 Convertible (RWD)

ST Suspensions is known for providing well-built suspension components, and their ST XA Coilover kit is a prime example of that commitment. If you're looking to dial in the stance and handling of your 2007-2013 BMW 328i (E91 Sports Wagon or E93 Convertible), this kit offers a significant upgrade over stock. It allows for precise adjustments to both ride height and damping, giving you the control to fine-tune your car's driving dynamics for a sportier feel or a more comfortable ride.

What sets the ST XA 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 unique combination prevents corrosion between the strut and perch, ensuring that you can adjust your ride height for years to come, while the stainless steel insert provides solid strength. Each damper is tested on a shock dyno at KW's facility in Germany before it's boxed, so you know they're performing to spec right out of the gate. With 16 distinct clicks of adjustable rebound damping, you can easily refine how your car handles everything from daily driving to spirited runs on winding roads. The galvanized zinc-coated steel struts offer robust corrosion protection, and an integrated dust protection system keeps dirt and debris away from the hardened chrome piston rod and valve packs.

This kit is designed to give you a lot of control over your vehicle's performance and appearance. You'll receive detailed instructions for setting the damper adjustments, making it straightforward to achieve your desired driving characteristics. The kit includes elastomer bump stops with integrated dust protection to help maintain ride quality and durability.
