*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
・This is a serious low-down suspension kit for serious dress-up users.
・We set them harder than the C-Wagon setting to prevent from bad driving feeling by more weight of big wheel installation and also to prevent the aero from scratching the ground when an over rolling occur.
・We used pillow ball for the front upper and camber adjustment function to have more option for setting.
・Even with the testing vehicle height, depending on the driving situation, front inner fender and tire could interfere each other. (Need an inner modification.)
・Please do not set the front case height lower than 292mm for it's the maximum limit of tie rod and body.
・Be careful not to make the rear damper case shorter than 336mm, for the arm and the body will interfere each other.
・The lowest value is the value of spring installation without the rear ride height adjuster
・The vehicle height data from other than the test is computational data.(The numbers does not guaranteeing the height)
