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 your vehicle only has springs at the rear as standard, this kit will also be the case. The struts are made of galvanized steel.

Only STXTA models are sold with strut mounts: for any other model, use the original strut mounts. Kits are supplied bare (shock cartridges and springs where applicable), unless an accessory essential to lowering is required. ST Suspensions is a KW brand, which manufactures these products.

Technical note before ordering

On models equipped with M-Tech, only use lowering springs: the lowering will be 20 mm less than indicated. These indications do not apply to models equipped with ride height correction, unless an adjustment of the ride height correction is made.
