Race Start Procedure:
The BMW's will hit Start to ghost after the 3-2-1-Go countdown. The Vipers will pull away and stay in the same order as dictated by the 1 quali lap we're doing. The Vipers will stay in this order and do 2 laps at 70% race-pace.
When the Vipers reach the final chicances 90deg right-hander (Arnage) on their 2nd lap, the BMW's will proceed in staggered formation, and their race will begin when the pole sitter crosses the Dunlop tire in the 1st sector.
The Vipers will resume staggered formation and slow to 80mph/130kph at the final chicanes. They will also start when their pole sitter crosses the Dunlop tire.
By starting the Vipers behind the BMW's on-track, there will be more time allowed for the Viper pack to spread out when the BMW's have their first encounter at overtaking the slower class.
