Points were awarded to the top 10 finishers in the order of 20-15-12-10-8-6-4-3-2-1. Manufacturers were only given points for their highest finishing car; any other cars from that manufacturer were merely skipped in the awarding of points.
Group 5 Sports Cars and Group 4 Grand Touring Cars were awarded points for the overall championship, but the GT class also had their own separate award.
Cars participating in races that were not included in the Sports or GT classes (such as Group 2 Touring Cars) were skipped when awarding points for the overall championship.
Only the best 8 points finishes counted towards the championship, with any other points earned not included in the total. Discarded points are shown in brackets.
