ST 1820220867 Coilover Kit ST XTA Plus 3 for BMW M3 (E90/E92) 2005-2013

ST 1820220867 ST XTA plus 3 coilover suspension, galvanised steel (damping adjustable with top mounts)

The ST suspensions XTA plus 3 coilovers are engineered for maximum suspension adjustability and performance, combining advanced KW damper technology with motorsport-oriented components. The system features independently adjustable rebound, low-speed compression, and high-speed compression damping, allowing precise tuning to suit different driving conditions, vehicle setups, and track requirements.

Damping adjustment includes 16 clicks for rebound and 24 clicks each for low-speed and high-speed compression, enabling fine control over chassis behavior under varying loads and driving dynamics. The inclusion of aluminum uniball top mounts allows camber adjustment, further enhancing front axle geometry setup and handling precision.

Ride height is adjusted via a continuous threaded galvanized strut, allowing precise lowering within the tested range, even after installation. Based on a twin-tube damper design with low-friction internals and pressure-resistant housings, the system ensures consistent performance and durability. A mono block guide and sealing package protect against contamination and corrosion, supporting reliable operation in all weather conditions.
