*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
For those who enjoy the track with S660, we tested without allowing any compromise.
We assumed a range from general high-grip radial tires to the higher class, A052, and tested the spring rate from 6 to 10 kgf/mm. the best result we obtained are the front 6 kgf/mm and rear 9 kgf/mm.
While riding with this kit, it feels like street driving go-kart. It balances both of the tire grip and the steering controllability at your will. You can enjoy this kit from track to street driving.
Because S660 is unavailable to load the spare tire, this kit is set up to make the stable riding comfort even with high grip tires on street driving. In spite of tightening the damper force adjuster, you still can drive comfortably on the street.
For customers who have changed their front tires to 195 size, the adjustable upper mount, which was previously available as an option, is a standard equipment now.
For those who aim for faster driving, we recommend a rate increase of +2 kgf/mm of front and +1 kgf/mm of rear.
Please note that the vehicle height at testing does not meet the minimum ground clearance of Japanese vehicle inspection.
