I think maybe a 3 run back to back set up for the 10.0 class...no cool off time except when driving back and waiting to line up, then take the average of the 3 runs, and run the closest times against each other, 1 vs 2, 3 vs 4, etc....i think it would be the closest competition for that class...but i think the bikes should have a class only if they can get 10 or more bikes to show up...other than that i think it makes for great fun for the cars to try and outrun the bikes on the top end.
