*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

・The spring rate is a little high as 16kg, but the leverage is high and the damping force for bumping is set low, therefore it has less reaction to the road surface and have comfortable drivability.
・It’s not as hard as it seems for the rate, but set to move effectively. We set it for smooth rolling.
・To have a good rear stability, we set the stroke allocation and damping force for better braking and stable traction. It’s also set to have easy and smooth reverse steering control.
