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.

Point
・If it set to less than the limit level of case length both front and rear will interfere with body when full stoke. ・MAX IV has accomplished the concept of both comfort and sporty characteristic. ・Didn't cut the normal drive performance and still have the great comfort in driving. ・Both front and rear has enough stoke for traction. ・If you drive town often can have comfortable drive with MAX IV dial setting at 30 step which let you drive very smoothly. (for winding roads or sporty drive, set at 15th step)
