How do I adjust the ride height and damping on these coilovers?

Ride height is adjusted using the composite spring perches on the strut body. The rebound damping can be adjusted using the knob on top of the damper, offering 16 distinct clicks. A detailed manual is included to guide you through the process.

What materials are used in the spring perches and struts?

The spring perches are made from a durable polyamide composite with a stainless steel insert, which prevents corrosion and maintains strength. The strut housings are made of galvanized zinc-coated steel for improved corrosion resistance.

Are these coilovers suitable for daily driving?

About this part

Product Details

If you're looking to dial in the stance and handling of your 2017-2020 Audi A4 Sedan, these ST XA coilovers are a solid option. They allow you to precisely set your vehicle's ride height and fine-tune the damping characteristics, giving you control over how your car feels on the road. This means you can achieve that aggressive lowered look while also improving road control without sacrificing too much comfort.

What sets these apart is the adjustability. You get 16 distinct clicks of rebound damping adjustment, controlled by a simple knob. This lets you tailor the suspension's response from comfort-oriented to sportier settings. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the perch and the strut body, ensuring that you can adjust the height for years to come, while the stainless steel provides the necessary strength. The galvanized zinc-coated steel struts offer good corrosion protection, and a built-in dust protection system keeps dirt and debris away from the piston rod and seals, helping to maintain the damper's performance over time.

These coilovers are built by hand by the experts at KW in Germany, and each damper is tested on a shock dyno before it's boxed up. You'll also find a detailed manual included that explains how to adjust the damping settings, making it straightforward to reset them to the factory recommendations or experiment with your own preferences. Everything you need to get started with height and damping adjustment is included in the kit.
