What is the benefit of having 3-way adjustable damping?

3-way damping adjustment allows you to independently control high-speed compression, low-speed compression, and rebound. This offers a much finer level of tuning for your suspension, letting you optimize handling for different driving conditions, from street comfort to track performance.

Does this coilover kit include everything needed for installation?

The kit includes the coilovers with adjustable spring perches, aluminum unibal top mounts, linear race springs, and elastomer bump stops with dust protection. It is recommended to refer to the manufacturer's installation instructions for any additional hardware or tools that may be required.

How do the aluminum unibal top mounts affect steering?

Aluminum unibal top mounts replace the stock rubber mounts, offering a more direct connection between the steering wheel and the wheels. This results in improved steering response and feedback, allowing you to feel more of what the road is doing.

Product Details

ST Suspensions is known for providing performance suspension components that offer a great balance of adjustability and durability. This XTA-Plus 3 coilover kit is designed specifically for the 2008-2013 BMW M3 (E90/E92/E93) and gives you the tools to fine-tune your car's handling for both street driving and track challenges. It's built with KW dampers, a company renowned for its high-performance suspension technology, ensuring you get a well-built system that can handle whatever you throw at it.

What really sets this kit apart is the extensive damping adjustability. You get 24 distinct clicks for both high-speed and low-speed compression, plus 18 clicks for rebound adjustment. This level of control allows you to precisely dial in your suspension to match your driving style, track conditions, or even modifications like a roll cage or spherical bushings. The ride height is easily adjusted using a seamless thread on the galvanized strut housing, even with the kit installed, thanks to the composite spring perch with an embedded stainless-steel insert. This perch is designed to be wear-resistant and friction-optimized, preventing oxidation and ensuring smooth adjustments.

This kit also includes linear race springs for consistent response and aluminum unibal top mounts that improve steering feel and allow for camber adjustments. Each damper is built by hand at KW in Germany and tested on a dyno to ensure it meets proper force specifications. The galvanized steel housing is sealed multiple times for longevity in all weather conditions, and the integrated dust protection system on the elastomer bump stops helps keep dirt and water away from the piston rod and seals.
