Installation and shipping

The coilovers are supplied in sufficient quantity to fit the vehicle and fit in place of the original suspension, without modification. If the vehicle only has rear springs as standard, the same will apply to this kit. The kits are supplied bare (shock cartridges and springs where applicable), unless an accessory essential for lowering is required. Only STXTA coilovers are sold with strut mounts: for any other model, original strut mounts are required for fitting.

ST Suspensions is a KW brand, and products of this brand are manufactured by KW.
