*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
Handling performance has been improved by applying the compression damping force as much as the body rigidity allows.
By adding the compression damping force, unnecessary extension damping force can be removed. The suspension is able to move more flexibly and unnecessary rolls are suppressed.
With flexible suspension movement, you can drive on any type of road in a comfortable manner.
Because the suspension is flexible and does not stretch, the setting is to maximize the grip of the tire.
Insulators are adopted as standard, with consideration for ease of adjustment and noise countermeasures.
・At the time of testing: F:D=10,R:D=10
