Points system

Championship points were awarded at each round on a 9-6-4-3-2-1 basis to the first six finishers in each class, and on a 4-3-2-1 to the first four finisher outright, irrespective of class.
At rounds which were contested over two heats, round placings were determined by allocating "points" to the first fourteen placegetters in each heat on a 20-16-13-11-10-9-8-7-6-5-4-3-2-1 basis.
Where more than one driver attained the same total, the relevant round placing was awarded to the driver gaining the higher place in the last heat.
Actual championship points were then awarded based on the calculated round placings.
