Fitting and delivery

The coilovers are supplied in quantity sufficient to equip the vehicle and fit in place of the original suspension, without modification. If your vehicle only has rear springs as original, this kit will be the same. Only STXTA models are sold with strut mounts: for others, use original strut mounts. Kits are supplied bare (shock cartridges and springs where applicable), unless an accessory essential for lowering is required. ST Suspensions is a KW brand, and its products are manufactured by KW.

Technical note before ordering: on vehicles fitted with electronically controlled suspension, make sure it is disconnected. A disconnect kit is available in the KW accessories range, part no. 68510145.
