*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 long-awaited HIPERMAX R, which is born with the latest theory in addition to cultivated through HIPERMAX IV SP, is newly released.
The new SRF (Super Response Fluid) and LVS (Low Vibration Spring) have been adopted to achieve unprecedented levels of both driving and ride comfort.
The newly adopted retainer, which blocks the spring load and eliminates the bending load on the spring and absorbs torsion to improve the movement of damper, enabling the LVS (Low Vibration Spring) to demonstrate its performance in any situation.
New internal components allow for a wide range of settings with a large amount of dial range.
Spring insulators in the front and rear have been installed to make ride-height adjustment easier.
We have done the setting at Fuji Speedway with ADVAN A052 tires. The damper force range is 10-click of front and 5-click of rear. Please refer it when driving on track.
If you concerned about riding comfort on the street, we recommend lowering the rear rate to 16 kgf/mm.
Although it is possible to change the spring rate when being shipped from factory, therefore, it is a possibility that the ride quality, driving feel, and understeer/oversteer characteristics may not be what was intended by the development team, so we recommend a standard rate or 2kgf/mm lower for the rear only.
Please experience the evoloved HIPERMAX!
