ST XTA Adjustable Coilovers 2015+ BMW M3 (F80) / M4 (F82)

The adjustable spring perch on these ST XTA coilovers is made from a durable, friction-optimized polyamide composite with a stainless steel insert. This design prevents corrosion between the strut and perch, ensuring that you can adjust your ride height for years to come, while the stainless steel insert adds strength and confidence.

These ST XTA coilovers are built by hand by experts at KW in Germany. Each damper is tested on a shock dyno before it ships to ensure it's making the proper forces. The galvanized zinc-coated steel struts offer improved corrosion protection, and an integrated dust protection system keeps dirt and water away from the piston rod and seals. You get 16 distinct clicks of adjustable rebound damping, allowing you to fine-tune your car's driving dynamics. The kit also includes aluminum unibal top mounts that let you adjust the camber at the front axle, which is crucial for dialing in aggressive wheel and tire fitment and maximizing tire contact patch for better grip.

With linear race springs and adjustable dampers, you can easily dial in your car's behavior to suit your driving style, whether you prefer comfort or maximum performance. The kit comes with a detailed damper setup manual to help you reset to factory recommendations or experiment with your own settings.
