*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
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 receives 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.
Special color insulators with a sporty image have been adopted to the front spring seat to create a striking appearance and improve slide during ride height adjustment, making adjustment easier.
In order to meet the needs of driving with high-grip radials, which has become increasingly grippy in recent years, ADVAN A052 are installed and tested on Fuji Speedway. We design to bring out the limit of tire grip by equipping this kit.
The recommended damper force adjusters on Fuji Speedway test are 10-click of front and 10-click of rear. Vehicles with Limit Sprit Differential are also supported. The plenty of room for damper force tightening has been set up. Please refer it while adjusting.
The negative camber at the maximum adjustable range has been set up during the test. With the negative camber, please make sure whether the brake hose and ABS harness are interferenced before driving.
The Applied A model car had been tested before, however, the front lower arm bushings have been changed to pillow bushings in the new year and this is a standard improvement for users who want a better handling, we conducted the test by euipping the lower arms with pillow bushings.
