Point Based on the 20SPEC, further improvements have been made and refined. This time, we set it up with the suppression during the swell, further improving ride comfort, and achieving a high level of balance with sports performance. By using the PVS and high flow rate needle, we have succeeded in creating a more ideal damper force characteristic. By reviewing the suspension rate, we were able to create a suspension kit that is easy to use from comfort to sport. Testing was conducted on a car equipped with NISMO arms.
