How do I adjust the ride height with these coilovers?

The ST XA coilovers feature a composite spring perch with a unique trapezoidal thread pitch on the strut body. This design makes ride height adjustment straightforward. You'll typically use a spanner wrench (often included or available separately) to turn the perches up or down the threaded strut body.

What is the benefit of adjustable rebound damping?

Adjustable rebound damping allows you to control how quickly the suspension extends after being compressed. With 16 distinct clicks, you can make the ride firmer and more responsive for sporty driving, or softer and more comfortable for daily use, tailoring the car's feel to your preference.

What is included in the ST XA Coilover Kit?

The kit includes the necessary coilovers with adjustable spring perches and damping, bump stops with integrated dust protection, and a detailed damper setup manual. It is designed as a complete suspension upgrade for the specified Cadillac ATS models.

Product Details

If you're looking to dial in the stance and handling of your 2013-2019 Cadillac ATS, the ST XA Coilover kit is a solid option. This kit lets you precisely adjust both the ride height and the damping characteristics, giving you control over how your car looks and feels on the road. It's designed to give you enhanced road control without sacrificing too much comfort, making it suitable for daily driving or spirited weekend cruises.

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 your ride height for years to come. The galvanized zinc-coated steel struts offer good corrosion protection, and a dust protection system is included to keep dirt and debris away from the hardened chrome piston rod and internal damper components. Each damper is tested on a shock dyno before shipping to ensure it meets factory specifications, and you get 16 distinct clicks of adjustable rebound damping to fine-tune your car's driving dynamics. A detailed manual is included to help you set and reset the damping to your preference.

This kit is built by hand by experts at KW in Germany, and it comes with an elastomer bump stop that includes an integrated dust protection system. This helps maintain ride quality and durability by limiting excessive suspension travel and preventing contaminants from reaching the seals. The kit includes everything needed for installation, and the adjustable rebound damping puts you in control of your car's comfort and sportiness.
