*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
・We have tested many times for the best setting for both of street and circuit drive based on MAX III Sport 09 with newest technology of MAX IV.
・We have tested with high-grip tires such as NEOVA 08R.
●Modification for installation
・Need a hole to put through the rear damping force adjustment cable.
