*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 developed a sport damper of MAX IV SP for Z33 from the scratch.
Plan 1. Changeable rear rate.
Plan 2. Easy damping force adjustment
To have rear stability for turn-in, we setφ65 series-wound spring with helper and enough bump stroke. Also we set the rear damping force adjustment dial inside the car for fast and easy setting, so that you don’t have to get your hands dirty (need interior works). We set it smooth but firm for the comfortable drive. It’s tight but not uncomfortable and there isn’t bad up and down movement. It also recovers fast.
Preferred dial setting
0-10: Circuit or high speed drive, 11 -20: Winding roads or highway, 21 – 30: Normal drive
We recommend spring rate of 14k for rear if you don’t go...
