ST X/XA Suspension Coilover Kit for BMW F20 F22 F30 M135i M140i M235i M240i 340i
Product Description
The ST XTA Coilover Kit is a performance suspension upgrade for compatible BMW F2X M-lite models, including the BMW F20/F21 M135i, F20/F21 M140i, F22 M235i and F22 M240i. Designed for drivers who want improved handling, adjustable ride height and greater suspension control, the ST XTA combines road usability with proven KW damping technology.
The kit features externally adjustable rebound damping, allowing the suspension to be set firmer or softer depending on road conditions, driving style and intended use. Increasing rebound can help improve stability and reduce body roll during more focused driving, while reducing rebound can make the car feel more compliant for everyday road use.
Ride height is adjusted using 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 an engineered coilover setup.
Where applicable, the ST XTA kit includes adjustable aluminium uniball top mounts, allowing camber and caster adjustment depending on the vehicle setup. This is especially useful for drivers looking to improve front-end grip, steering response and alignment precision.
Built around a low-friction twin-tube damper design, the kit uses galvanised damper bodies with additional corrosion protection coating for durability in road and performance use. Supplied as a complete suspension solution with front coilover assemblies, rear dampers, rear lowering springs, height adjustment components, bump stops and dust protection, the ST XTA is a strong option for fast road and occasional track-focused BMW builds.
Professional installation, ride height setup and full wheel alignment are required after fitting to correctly configure the suspension geometry.
