Top-6 cars are inverted in each heat race based on qualifying results.  The fastest car starts 6th, the second fastest car starts 5th and so on.  For the 4th row on back, cars will line up straight up, based on their qualifying times. If there are 30 cars or less, three heats will be held. If there are 31 cars or more, four heats will be held.

12 laps. The 14 fastest cars in qualifying that did not transfer through the heat races will line up straight-up in the semi-feature event. Finishers 1-6 earn a spot in the feature event if 4 heats were held. Finishers 1-7 earn a spot in the feature event if 3 heats were held.

FEATURE:

30 laps. Starting positions determined by qualifying time, 6 fastest at the front, with the 6 fastest qualifiers who transferred through their heat races inverted by their qualifying time in the first three rows, positions 1-6.  If a heat race winner is not in the top-6 inversion, that driver will line up directly behind the six-car invert, based on their qualifying time, followed by the balance of the field based on qualifying time. 22 starting cars (not including earned provisionals).
