The HSD coilover kit for VT-VZ Holdens offers fantastic performance and quality at an affordable price, backed by a 12-month, unlimited kilometre warranty and full after-sales service and support by Otomoto. Our kit uses mono-tube dampers, with 44mm pistons. The dampers have 16-step adjustment, with a clear difference felt for every step. Spring rates are aimed at club-level racing, but still compliant enough for every-day driving. We keep the rear springs relatively soft to maintain good traction. The front coilovers come with an upgraded version of the original holden top mount, as the original mounts are usually too worn to re-use. Spring preload and base height can be adjusted separately so the ride and travel are the same at any height. The front swaybar link height is also adjustable to suit your selected ride height. A second swaybar link is included to suit the different mounting type of VZ series 2. At the rear the original top mount for the shock is retained, while an adjustable spring seat bolts on to the trailing arm. For lower ride height the lock ring can be removed, however handling and grip are compromised when these models are lowered too far. Please note that this kit can not be used in wagon or ute versions of the VT-VZ.
