| Point |
| This product utilizes an adjustment dial that allows various driving conditions from street to circuit with high grip radial tires. For further performance improvement, this product was developed with latest parts such as new shape needle, M-shaft, aluminum bracket, etc. based on Hipermax III Sports 09 Spec, Its adequate stiffness of the damping force enables the smooth cornering. Also, the setting was performed to take a load toward the rear at the exit of the corner. No upthrust over the level difference of a road and stable vehicle movement without floating feeling can be provided, which maintains the comfortable driving on a street. The helper springs are installed on both front and rear. The rebound stroke for the spring rate is sufficient so it provides superior road surface follow-up property and stability in the criteria zone, and has a positive effect on traction. Its smooth rear sliding is distinctive. Adjust the dial to 10-15 for circuit driving, to 15-20 for street driving, and to 20-30 if better ride quality is prioritized for other passengers. Since the front damper is close to the front tire and wheel, make sure the damper does not come into contact with any other parts of a vehicle when lowering the vehicle height. If the damper comes into contact with any other parts of a vehicle, slide the tire wheel outward using a wheel spacer or a similar tool. The rear case length is set to the lower limit before shipment; it cannot be shorter. To lower the vehicle height, adjust the preload. |
