*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
・It didn't give up the driving performance and at the same time it provides comfort in town driving. MAX IV has advanced even more from the MAX III.
・We have adopted newly developed needle and variable port system for both front and rear that makes damping force at the low speed range, which is very important for comfortable and great steering with no upthurst and floating feel.
・With the new design of piston and M shaft for rear damper provides better oil pressure that gives comfortable dive.
・The damping level can be adjusted with dial for slow drive or winding road drive or all other type of situation.
・The normal rear damper has not so good driving experience but the MAX IV provides awesome feeling and performance in dri...
