The SC is equipped with an electronic suspension control. You can definitely feel a difference in the ride when you switch from the soft and sport (Firm) setting. The ride control system is made by Tokico. A computer monitors vehicle speed, brake-line pressure, steering angle and engine-computer acceleration signals to determine the shock valving. There are two switch settings. These settings are: Auto and Firm. The automatic setting selects soft shock valving for a smooth, comfortable ride. When driving conditions require a firm ride, it automatically overrides the soft valving. The firm position is simply an override that selects the firm setting in all driving modes.
