*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
For normal daily drive, it's ok. But if you drive fast the ride gets a little bumpy and the rear recover too fast. So if the comfort is what you want, this could be too stiff. For the steering for a corner, as roll gets deeper and deeper, the stability and grounding is not steady and even in an extreme condition where the electric control kicks in, the vehicle goes under side and unstable as it reverse. The stock is not comfortable or safe in a high speed drive.
So we have developed MAX IV GT for cool low stance style and to support a vehicle's its maximum potential performance. We have adjusted all four wheels damping force rate, allocated stroke, vehicle height balance and etc. by doing many tests. These tests result in a stable and balanced pressure for each wheel. All these setting will provide driver the best performance of the vehicle with safety. Also we have set the damping force and piston speed for good comfort. We recommend the dial-30 for most comfortable drive.
