*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
・To be further ultimate suspension, both the front and rear stroke were extended, and the supple and tractable stroke creates persistent and stable grip and adequate load shift. Rally driver Mr. Toshihiro Arai joined testing and his experience and feedback was utilized to finalize the setup. Turning up the adjustment dial makes this suitable for light circuit use. Whilst the spring rate is 1kgf/mm softer than MAX IV GT, the bump rubber acts as a 2kg spring from compressions beyond 1G which can help eliminate unnecessary pitch and roll. A smooth and predictable stroke delivers the joy of pure driving through controllable weight transfer on the limit.
・The best handling dial position Rally driver Mr. Toshihiro Arai selected at the time of testing at Gunsai is 04 for the front and 08 for the rear.
・The value within the parenthesis under the stroke section is the stroke length to the bump rubber. (Actual value may be different.)
