*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
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. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point

We updating the new MAXIV GT 20 SPEC for ND5RC/NDERC for improving comfortability and handling based on the existing MAX IV GT.
Improved steering performance as far as a body rigidity due to the increased damping force.
Increased damping force of the suspension and limited maximum damping force results in smoother suspension movement and eliminates excessive body roll.
Smooth suspension moving also provides more comfortable street driving on various roads and conditions.
This suspension set-up brings out the maximum wheel grip force with smooth suspension moving without excessive stiffness.
Adopting a special insulator as a standard allows easy adjustment to countermeasure abnormal sounds.
