*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
"Ultimate Street Damper" developed under supervision by rally driver Mr. Toshihiro Arai. The stroke is extended to 13mm in front and 26mm in rear, and the bump rubbers act as 2kgf/mm sub-springs so the handling and road holding performance are much better than expected. The supple and tractable stroke creates persistent and stable grip and adequate load shift
The best handling dial position Rally driver Mr. Toshihiro Arai selected at the time of testing at Gunsai is 15 for the front and 00 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.)
The vehicle height data from other than the test is computational data. (The numbers does not guaranteeing the height)
