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 using the knob at the top of the damper, offering 16 distinct clicks to change the firmness of the ride.

What is the benefit of the composite spring perch?

The polyamide composite perch with a stainless steel insert prevents corrosion between the strut and perch. This ensures that the ride height remains adjustable over time and provides a strong mounting point.

Does this kit include everything needed for installation?

This kit includes the height-adjustable coilovers with adjustable rebound damping. It is recommended to consult the manufacturer's installation manual for any additional hardware or tools that may be required for proper installation.

About this part

Product Details

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

These coilovers are built by hand at KW in Germany, and each damper is tested on a shock dyno before it ships out. You get 16 distinct clicks of adjustable rebound damping, allowing you to fine-tune your car's driving dynamics. Whether you prefer a sportier feel or a more comfortable ride, these coilovers put the control in your hands. The galvanized zinc-coated steel struts offer solid corrosion protection, and a dust protection system keeps dirt and debris away from the hardened chrome piston rod and valve packs, all supported by a multi-layered sealing package.

This kit is designed for the 2017-2020 Audi A4 B9 Sedan with 2WD and without electronic dampers. You'll find a detailed damper setup manual included, making it easy to reset to recommended settings. They come preset from the factory to our tested damper settings.
