What is the benefit of the aluminum unibal top mounts?

The aluminum unibal top mounts improve steering response and feedback. They also allow you to adjust the camber on the front axle, which helps dial in aggressive wheel and tire fitment and maximize tire contact for better grip.

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

Ride height is adjusted using the spring perch located on the strut body. The rebound damping can be adjusted with a simple turn of the knob on the damper, with 16 distinct clicks available to fine-tune your car's handling.

What is included in the ST XTA Coilover kit?

The kit includes height-adjustable coilovers with linear race springs, adjustable dampers, aluminum unibal camber adjustable top mounts, and a detailed damper setup manual. It also features integrated dust protection systems.

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 helps prevent corrosion between the strut and perch, ensuring that you can adjust your ride height smoothly for years to come. The stainless steel insert adds strength and confidence to the adjustment mechanism.

These ST XTA coilovers are built by hand by experts at KW in Germany, and each damper is tested on a shock dyno before shipping to ensure it meets proper force specifications. The kit includes linear race springs for consistent response and aluminum unibal top mounts that allow for front axle camber adjustment. This lets you fine-tune your wheel and tire fitment and maximize tire contact patch for better grip, especially in fast corners. You also get 16 distinct clicks of adjustable rebound damping, letting you easily dial in your car's driving dynamics to match your preference, whether that's for comfort or performance. The galvanized zinc-coated steel struts offer good corrosion protection, and a dust protection system keeps dirt and water away from the hardened chrome piston rod and seals.

This kit is designed for the 2008-2013 BMW M3 (E90/E92/E93) without EDC. It includes everything you need to adjust ride height, camber, and rebound damping, giving you precise control over your car's handling and appearance.
