How do I adjust the ride height and damping?

Ride height is adjusted using the composite spring perch on the strut body. The rebound damping can be adjusted via a knob on the top of the damper, with 16 distinct clicks available.

What is the benefit of the aluminum unibal top mounts?

The aluminum unibal top mounts allow you to adjust the camber angle on the front axle. This is useful for optimizing tire wear, improving cornering grip, and fitting wider wheels and tires.

Are these coilovers built to last?

Yes, ST XTA coilovers are built by hand by KW in Germany. They feature galvanized steel housings for corrosion resistance, a composite spring perch that prevents oxidation, and a dust protection system to safeguard internal components.

Product Details

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 coilovers are built by hand by the experts at KW in Germany, and each damper is tested on a shock dyno before shipping to ensure it meets proper force specifications.

With 16 distinct clicks of adjustable rebound damping, you can easily refine your car's driving dynamics to suit your preference, whether that's for comfort or performance. The included aluminum unibal top mounts allow you to adjust the camber on the front axle, which is crucial for dialing in aggressive wheel and tire fitments and maximizing your tire's contact patch for better grip in corners. The galvanized zinc-coated steel struts offer excellent corrosion protection, and a dust protection system with elastomer bump stops keeps dirt and water away from the hardened chrome piston rod and seals.

This kit is designed for a range of BMW 3 Series models, including the E90 Sedan and E92 Coupe. You'll get linear race springs for consistent response and the ability to easily swap rates if you want to personalize your setup further. The kit comes preset to factory-recommended damper settings, and a detailed setup manual is included to help you reset them anytime.
