Point

・We have tested many times for the best setting for both of street and circuit drive based on MAX III Sport 09 with newest technology of MAX IV.
・We have tested with high-grip tires such as NEOVA 08R.
 
●Modification for installation
・Need a hole to put through the rear damping force adjustment cable.
