The ride comfort required for daily use and sports performance such as stability has been improved in a well-balanced tune without losing stock comfortability Pursue a drivability at the specification setting, We could create suspension that the car movement easier to understand and allows the driver to have better control. Testing various spring rates resulted in a suspension with a spring rate of F = 69 Nm (7 kg)/R = 59 Nm (6 kg) and a spring length of F = 200 mm (series barrel type)/R = 250 mm (series barrel type) that was suitable for a wide range of users Increase high rates springs are required for use in hill climbs and mini truck or use with high grip tires (ex Yokohama A052).
