* 1. Height from the road surface to the fender arch.
* 2. The vehicle height at the time of shipment is reference measurement value data based on the combination of full kit settings within HKS. (This is our recommended vehicle height.)
* 3. Adjustable range (However, please note that driving at the lower limit in this case is out of compliance with safety standards.
Also, even if it is within this adjustment range, the vehicle Depending on the height, it may interfere with the body, arm, etc. and hinder driving. In
addition, we guarantee against problems such as damper oil leakage due to use with the vehicle height extremely lowered from the factory height . Please note that it is not applicable.)
* 4. The range in which the vehicle can run without interference with the body, arm, etc. (However, this does not apply depending on changes in tire and wheel sizes, etc.)
Note). Data will change depending on individual differences and assembly conditions of the vehicle.

■ Point
The MAX S for BNR32, which has evolved further from 20SPEC, has been set.
We pursued driving with a sense of unity with the driver by further improving the hardness and connection feeling of the valve that feels the damping transient.
By optimizing the size of the PVS, we controlled the damping curve exceeding 20 SPEC.
The color has been changed to gunmetal in line with the renewal, and the chamfering process of the upper plate has been added to further improve the aesthetic appearance.
● Processing at the time of installation
Hole processing (rear interior) for the rear damping force adjustment dial is required.
