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.)

・We could have less weight by changing the both front and rear bracket to aluminum, same as the MAX IV GT which was steel originally.
・Our new design of needle which was first developed for MAX IV GT is used here too. It will improve ride comfort and control by having better performance of damping force in a low RPM.
・The high spring rate with helper spring will have enough stroke in the s...
