*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
・Increasing 1 kg of spring rate of front and rear from MAX III enhances the stability during high speed driving furthermore.
・Focusing on the ride quality leads to the product quality improvement, and gradual suspension movement is pursued.
・Adequate posture change and supple damping strike balance between riding comfort and sportiveness while maintaining the vehicle's high-quality image.
・Smooth and non-fluffy vehicle movement is provided so driving becomes comfortable for all passengers.
・Soft and gradual movement enables the driver easily to know the load changes so a car becomes more capable of fast cornering on a winding road under S# mode and to drive dynamically
・Recommended dial position is 13-15 in front and 20 in rear.
・The vehicle height is only calculated numbers except the height at the test. (It does not guarantee the actual height.)
