*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

・Further improvement of the driving performance and quality for daily driving and even for circuit driving is attained maintaining the original well-balanced ride quality and sporty performance.
・The upthrust feeling commonly occurs with a light weight sports car is eliminated, and supple performance is achieved. Reliable performance, its exquisite driving posture, and controllable characteristics enhance driving pleasure.
・The damping force is widely adjustable: set the dial to 30 for the stock ride quality, set to 10 to 15 for light and sporty driving, and for spirited driving and circuit driving, set to 5.
・HKS traditional “inverted strut” was chosen for the front suspension; the driver can feel its high rigid suspension structure and great steering response.
・The length of each component is properly optimized. The damping force ...
