Product Description

The ST XTA Coilover Kit for the BMW E9X M3 2007–2013 is designed for drivers who want sharper handling, adjustable ride height and greater control over suspension setup. Using proven KW damper technology, the ST XTA system offers a strong balance of road usability and performance-focused damping control.

The kit features externally adjustable rebound damping, allowing the suspension to be tuned softer or firmer depending on the driving conditions. Increasing rebound can improve stability and reduce body roll for more focused driving, while reducing rebound can help improve comfort for road use.

Ride height is adjusted via a continuous thread system, allowing the car to be lowered within the tested adjustment range. This gives owners the ability to fine-tune stance, centre of gravity and handling balance while retaining a properly engineered suspension package.

For improved front axle precision, the ST XTA kit includes adjustable aluminium uniball top mounts, allowing camber and caster adjustment where applicable. This is especially useful for performance alignment setups where additional front-end grip, sharper steering response and more accurate geometry control are required.

The dampers use a low-friction twin-tube design with galvanised damper bodies and additional corrosion protection coating for improved durability. The kit also includes spring platforms, springs, bump stops and dust protection components as part of a complete suspension upgrade for the BMW E9X M3.

Professional installation, ride height setup and full wheel alignment are required after fitting to ensure the suspension is correctly configured.
