Years: 04/09-

Compatible vehicle power (in kW): 115-190

Maximum permitted front axle load (in Kg): -800

Maximum permitted rear axle load (in Kg): -970

Possible front/rear lowering (in mm): 30/20

Please note:

ST Suspensions shock absorbers and springs are supplied in sufficient quantity to equip the vehicle. They fit in place of the original suspension without modification. For example, if you only have original springs at the rear, the same applies to these ST Suspensions kits. Make sure to use the original strut mounts for installation. ST Suspensions kits are supplied bare (shock absorber cartridges and/or with springs as applicable), unless an accessory essential for lowering is required.

Shock absorber cartridges, however, are sold individually! You will therefore need to order at least 2 to equip an axle.

ATTENTION: compatible power ratings are expressed in kW (kilowatts). To convert to hp, use the following formula: 1 kW = 1.36 hp. Online converters are also available.

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