*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 damper kit for serious dress-up users.
・We set it harder, compare to C-Wagon, to avoid for the aero to hit the road at a high rolling and bad drivability for a heavy vehicle with big wheels.
・Can have more option setting because of the front upper mount adjustable camber adoption.(Camber setting at the test was max to the minus)
・The front tire and inner fender interfere with each other at the testing.(tire/wheel: 245/45-19、8J×19 off 38)
・If you make the front case length shorter than the minimum limit, the stabilizer and the frame will interfere at a full stoke or a full steering.(If you change the front stabilizer to the longer one, you can make the front case even shorter.)
・If you make the rear case length shorter than the minimum limit, the handbrake wire and the body will interfere.
・The data other than testing is calculated numbers.(It's not guaranteeing the actual number of vehicle height)
 
●Modification for installation
Need to cut the stock rear dust boot.
