About Test & Tune Events

Test and Tune Events are one day "closed" events, usually prior to a weekend club race or competition, for the purposes of engine tuning, dialing in suspension setup, and driver familiarization.

Those allowed on track are limited to competition licensed racers participating in the upcoming event that same weekend, driving race-prepared cars with current stamped logbooks and using all current safety equipment required by the race sanctioning body. Test & Tune events are operated under the rules of the race sanctioning body holding or requesting the Test and Tune.

Test and Tune dates will only be offered at the request of a sanctioning body and are not Open Track Days.

Test & Tune sessions and run groups will be determined by the requesting club or organization, with short intermissions for safety purposes. Drivers may run all sessions scheduled for their run group, pending a safety review by the Chief Driving Instructor and Chief Steward before each session.

The designation of a participant's run group is subject to the approval of, and reviewed by, the Chief Driving Instructor and Chief Steward.
