*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 set the spring rate high compare to other vehicle's S-style X because it has smaller clearance between the tire and body so that it will have less vehicle movement.
・Adjustable chamber pillow upper is used for front upper mount.
・Please set within 3 steps to the negative of the factory setting for the front chamber adjustment. If you set it more than that it will interfere with brake hose bracket and brake tube and it will be very dangerous.
・You might feel the vibration depending on the vehicle's front height.
・It might interfere with the fender and the tire for rear case length of less than 336mm.
・Recommendation of tested dial setting: front:15, rear:15
・To not to interfere with tire in such as rear fender modification, the maximum rear case damper length is 326mm. Torsion beam and brake hose is the limit.
