Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)

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 driving, especially for a town drive.
・Even setting the damping level to soft doesn't make it floating feeling so when having a long distance driving, you won't get tired and have a great comfort for the passenger.
・When you set the damping level to hard, you can feel directly of the step differrence and direct handling.
・Set damping level 20 to 25 for soft and 10 to 15 for hard setting.
