*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
Stylish low-down appearance with enhanced potential for high performance was focused on when developing this product. The stock suspension prioritized the ride quality; therefore, the damping force is rather low even under S or S+ mode. This characteristic may spoil the stability in situations such as high speed driving, cornering, and/or lane change.
This product can improve handling without impairing the riding comfort even after lowering the ride height. The stability is enhanced by taking into consideration not only of the spring rate or damping force but also the stroke.
For relaxing ride quality like the stock setting, set the dial at 20 to 30.
NAVI and AI-AVS functions are omitted, but this product has superior function as a suspension kit to these omitted functions. Settings were determined to make the product having higher potential with full consideration of what are required by users. Higher basic performance of this product can enhance its application ability so it enables to support a wide range of application.
