*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
The stock ride & handling is good in each mode, although there is a bit of fluffiness during daily use at legal speeds and up to a moderate pace without the electronic device control’s interference.
However, when driving at a slightly higher speed or in the high-load range, the car becomes unsteady and cannot be operated accurately, which reduces the enjoyment of driving. Also, if you drive the car to its limits, the electronic device control may interfere and does not allow the car to reach its full potential. Furthermore, if you change to tires with better grip, sometimes the electronic device will not intervene and the car will reverse suddenly, which can be dangerous. If the electronic device is turned off, the driver is still in control. While cornering at high speed, the vehicle may lose the tire grip. Because of the loss and getting of tire grip alternatively, it makes the fluffiness.
HIPERMAX S is designed to provide a more stylish appearance by lowering the vehicle, and to achieve a ride quality that is appropriate for a vehicle with performance that fully exploits its potential. After numerous tests of front and rear rates, damping, stroke volumes, ride height balance, etc., we aimed to give the tire grip to bring out the car's full potential and stabilize the limit characteristics. In addition, the damping value of the damper was also controlled by the piston speed to ensure ride comfort. If you want to prioritize the ride comfort, please try loosening the dial to about 30 click.
