Point
Further improvement of the driving performance and quality by resolving the delayed steering response, vehicle body roll in acceleration, and unrequired nose-dive at braking is attained maintaining the original well-balanced ride quality and sporty performance.
Several tests were conducted to eliminate the upthrust feeling commonly occurs with a light weight sports car and to achieve supple performance. Reliable performance, its exquisite driving posture, and controllable characteristics enhance driving pleasure. For your reference for setting, the test data for RSt is shown in the manual.
The recommended damping force adjustment dial position is 20 for both front and rear sides. For sporty driving, set to 10 to 15.
A collar is included to avoid unnecessary contact between the stabilizer link and bracket.
If the front case length is shortened less than the lower limit, the stabilizer may come in contact with the brake hose bracket at full-bump.
