*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 to avoid for the aero to hit the road at a high rolling and bad drivability for a heavy vehicle with big wheels.
・We have adopted camber adjustable upper mount for front. But because the hole at the vehicle side installation position it cannot have a camber adjustment to the maximum upper plate limit.
(Camber setting at the test was step 3.5.)
・If you make the front case length shorter than 321mm, the stabilizer and the body will interfere at a full stoke.
・Please do not make the rear damper case less than 321mm or it will interfere with wheel speed sensor connector and the torsion beam.
・The recommend dial setting for front:20 steps, rear:20 steps.
・The data other than testing is calculated numbers.(It's not guaranteeing the actual number of vehicle height)
