*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
MAX S for BNR32, a further evolution from 20SPEC, is now available.
In order to avoid fluctuated damper force shifting, causing uncomfortable feel under braking or corning, we tested and chose from the countless number valve shims to pursue a driving movement which the driver could feel as expected during driving.
By optimizing the size of the PVS, we control the damping characteristic beyond 20 SPEC.
The color has been changed to gunmetal to match the renewal, and chamfering of the upper plate has been added to further improve the aesthetics.
●About modification at the time of installation
Cutting cargo space is required to install the rear damper force adjustment.
