Point
・MAX III B.B.TUNE concept is the same and with many new technology inside.
・MAX IV setting has a comfort in driving, so you don't have to worry about lowering the automobile.
・MAX IV is made for both comfort and sport driving. You can use it for town drive with family member or have a thrilling drive at the winding roads.
・MAX IV is optimized for low speed damping force that let you have a high-quality driving experience. Also we have not set it too hard for the balance of rigid body.
・MAX IV provides safe drive with comfort when stock suspension has that bumpy feeling.
・The vehicle height data from other than the test is computational data.(The numbers does not guaranteeing the height)
・Spec B tire has bigger tire that when hit a big bump, tire and fender might interfere each other.
 
* Modification for installation
・Need to make a hole for rear damping adjustment cable(rear interior)
