Point
・MAX IV improved cornering adn still has the deriving comformt.
・The cornering performance has improved by changing front rate of 1k up and renewed the roll strength of MAXIII.
・We have tuned rear damper for better driving performance and comfort.
・The default setting for dial is 15 step for both front and back. If you want more comrfortable setting, set it to 25 to 30 step.
・It's easy to worn out because the floor of rear axle is lower. Please be careful not to lower too much.
・MAX IV is also good with A/T. Even at a winding road driving will be comfortable.
・The vehicle height data from other than the test is computational data.(The numbers does not guaranteeing the height)
