ST XA Adjustable Coilovers 09-16 BMW Z4 (Z89)

If you're looking to give your 2009-2016 BMW Z4 a more aggressive stance and fine-tune its driving dynamics, these ST XA coilovers are a solid choice. They allow for extensive adjustment of both ride height and damper settings, so you can really dial in how your car looks and handles. This kit is built by hand by the experts at KW in Germany, and each damper is tested on a shock dyno before it ships out to ensure it's performing correctly.

The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This design helps prevent corrosion between the strut and perch, ensuring that you can adjust your ride height for years to come. You get 16 distinct clicks of rebound damping adjustment, which lets you easily change how sporty or comfortable your Z4 feels. The galvanized zinc-coated steel struts offer good corrosion protection, and a dust protection system keeps dirt and water away from the hardened chrome piston rod and internal seals.

These coilovers come preset to factory-recommended damper settings, and a detailed manual is included to help you understand the adjustment options. You can easily set them up for comfort, sportiness, or anything in between, putting the finer details of your car's driving behavior directly in your hands. The kit includes elastomer bump stops with integrated dust protection to further enhance durability and maintain ride quality.
