*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
・HKS has set the MAX IV for both sportiness and comfort.
・We haven't spoiled stock's sportiness and improved the comfortable drive and also provides better control.
・We have improved the driving experience drastically compared to the old model by analyzing year 2012 model and VPS and new piston.
・We have improved driving performance of road-hugging property by high-rate + helper-spring. And improving the start-up damping allow comfortable drive and keep down the sudden pressure change.
・Set about 20th step for a comfort drive and about 5th step for a fast drive.
・If the length of case shortens below the lower limit value, it is likely to interfere with the upper arm and body. Also depend on the size of the tire wheel, it could interfere with fender even within the limits.
