*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
・We have set it for comfort in everyday drive. ・To reduce the attack on the body, we have set the lower rate. ・When driving mainly in the circuit or winding road, it is recommended to be used with increased rate of the spring. ・Recommended dial in town ride is the factory spring rate of 23 stage front and 18 stage for rear. ・If your car is installed with rear diffuser and rear member color, the minimum vehicle height is less than 90mm even at the point of shipping. ・The vehicle height data from other than the test is computational data.(The numbers does not guaranteeing the height)
