In order to be classified for points, a team had to complete 90% of the winner's distance. Further, drivers were required to complete at least 30% of their car's total race distance to qualify for championship points. Drivers forfeited points if they drove in more than one car during the race. Group C2 drivers earned extra championship points for any finish within the overall top ten positions.
