It is once again the largest Championship payout structure, which in turn makes NIRA the richest series in compact car racing. Drivers may substitute a different car prior to start of Qualifying, so long as it is within the same class, but once that car is qualified, another driver cannot take the helm or score any points with it nor can driver switch cars. Points cannot travel between classes.
Points travel with driver only within the same class.
In situations where driver has a bye-run, driver will be considered the winner only after he stages in accordance with staging rules and the light goes green. All applicable standards on staging, records procedures and event wins must be met for points to be awarded.
