HKS Hipermax Iv Gt Fd3s Full Kit
This is set for city street drive. HKS has redesigned the M shaft and inside of the damper that has improved driving experience and handling by pulling up damping fast from the start. The new design of rear upper plate give more adherence to the body.
The recommended setting for dial is 15 step for both front and back. If you want more comrfortable setting, set it to 25 to 30 step. MAX IV can handle from city street to winding roads.

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.)
