With on-road racing, it's important to make sure every setting is dialled in. Even the smallest different in set up will give you problems and add time to your laps. To help with handling, it's critical to make sure your droop setting is consistent. The Chassis Droop Gauge is often overlooked, but once you use it, you will see it makes the difference. You will also notice everyone coming to your pit station to check their droop with your tools as well. Scale Freak Approved.
