Fitting and delivery

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

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