*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point
20 SPEC for Alto Works has been added to our product line.
We have aimed to realize a flexible suspension that ensures smooth and stable driving even with lightweight vehicles by employing many of more flexible valves than the ones used in the existing model.
By using high flow needle for the damping adjustment part, it allows to offer wider range of damping adjustment to correspond to various driving situations.
Since the rear bump rubbers are made of hard rubber, pursuing ride comfort was not an easy task. However, by applying the maximum damping force to the contracting side of the damper and with the optimal spring rate, we have realized to secure the ride comfort.
Although the rear spring space of this vehicle is very narrow, having introduced a spacer adjustment method enables the adjustment by 10mm.
Please refer to the manual upon installation since modification of the OEM rear bump rubbers may be required depending on the ride height at the installation.
