Each competing car was classified into one of three classes.[1]
Series points were awarded on the following basis within each class at each race.[1]
Bonus points were awarded to each race finisher equal to the number of cars that started a race within that class. E.g. If 14 cars started a race in Class B, then each car that finished within Class B was awarded an additional 14 bonus points for that race.[1]
The driver gaining the highest points total from his/her best seven round results was declared the winner of that class.[1]
Any points scored by a driver within a class were not transferred if that driver changed classes.[1]
