*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
The product had been developed with testing many times while several kinds of springs and damping force settings trial. As a result, it can be provided the various damping force setting from the street to the circuit driving by changing the dial. This latest wide-range damping force setting provides a calm and smooth feeling under the solid grip and it aims improved control and stable performance even at the FR vehicle turning performance limit. The track driving tests were performed by the vehicle installed with YOKOHAMA TIRE, ADVAN A052_265/35-18 inch at the front and rear, also the front upper arm was changed in order to change the front camber 3°30' in a negative direction. The vehicle further installed LSD. The standard dial setting for high-speed circuit driving is 6 clicks from the stiffest setting. In street driving, please select in your preferred setting between about 15 to 30 clicks from the stiffest setting.
 
Note: The front damping force adjustment dial may become hot due to the heat from the engine room, please wear gloves when adjusting the dial.
