*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
Front camber values during testing are those adopting adjustable upper arms. Therefore, please use the above vehicle height information as a reference value because the vehicle height will change due to changing the camber values. If the calculated values do not result in the desired ride height, please have the vehicle alignment adjusted.
The new SRF (Super Response Fluid) and LVS (Low Vibration Spring) have been adopted to achieve unprecedented levels of both driving and ride comfort.
New parts are adopted internally to enable a wide range of settings with a large amount of dial range, resulting in higher durability.
We have done the setting on Fuji Speedway with ADVAN A052 tires. The best result of testing was obtained with 11-click in the front and 11-click in the rear. Please refer it when driving on track.
Front camber values during testing are those adopting adjustable upper arms.
Although it is possible to change the spring rate when being shipped from factory, however, 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 hope that you will enjoy the standard rate that we have carefully selected.
