STX Coilovers ST Suspensions BMW 1 Series

The STX ST Suspensions coilovers (ref. 1322000D) fit the BMW 1 Series (F20, F21), (1K2, 1K4), 2WD, without electronically controlled suspension, from 09/11. Derived from motorsport, the STX range offers precise height adjustment with a fixed damping rate set at the factory.

• Maximum permitted front axle load: 920 kg
• Maximum permitted rear axle load: 1230 kg
• Front lowering: 25 to 50 mm
• Rear lowering: 30 to 55 mm
• Height adjustment at the front and rear (on vehicles that allow it) via a disc on the threaded body of the shock absorber
• Strut legs in galvanized steel with anti-corrosion coating

Coilovers are supplied in sufficient quantity to equip the vehicle and replace the factory suspension without modification. If the vehicle has springs only at the rear from the factory, the kit will be the same. Kits are supplied bare (shock cartridges and springs where applicable), except for accessories essential to lowering. Only STXTA coilovers are sold with strut mounts: for other models, factory strut mounts are required for installation. ST Suspensions is a KW brand, which manufactures its products.

Technical note: on M-Tech models, only use kits with lowering springs. Lowering will then be 20 mm less than indicated.
