USAC/MSCS AMSOIL SPRINT CAR NATIONAL CHAMPIONSHIP FORMAT
Formats may be altered from base formats listed here at the discretion of the chief steward.
Drivers will qualify their cars in group sessions. The groups will consist of the cars as divided into heat races based on the pill draw. The maximum number of laps for each session would be 5 and the minimum number would be 3. Your best lap of the session will be your qualifying time.
10-lap race. In all heat races, the top-4 qualifiers will be inverted in the line-up with the remainder of the field starting straight up. A drawing will be held after the heats to determine the exact number of cars to be inverted at the front of the A-Main. The number of cars subject to the inversion drawing for the feature will be dependent upon the car count and the number of heat races needed and held. The top finishers in each heat race will transfer straight to the A Main. The decision on the number of drivers to transfer from each heat race will be announced and explained at the drivers meeting.
10-lap race. A C-Main may be utilized if needed. Transfers from the C to the B and the B to the A is by order of finish on the track.
12-lap Race. The B-Main will add the final qualifiers to the feature field. The cars will start straight up beginning with those that did not transfer to the A Main through the heats. The line-up for the B should allow for the addition of the top finishers transferring from the C.
22 starting cars (not including earned provisionals – up to each from both USAC & MSCS)
Cars that advanced through the semi-feature to fill the field will start straight up in the feature behind the cars that advanced through the heat races.
Drivers will earn feature points only in this event. No qualifying, heat race or semi-feature points will be accredited toward the season championship. Non-feature starters will earn appearance points only.
