There were 3 classes, Mod, Super Stock and Stock.
As far as the Mod class or Super Stock goes, James and Hobie are on the money. With that said, my car has mods on the rear suspension, yet met the criteria for Super Stock for this race based upon the stock 700 efi engine. It is not built! Nobody was cheating anyone. As it turns out, we/they didn't need to. I do agree with Jerimiah on one point, that the rules need to be better defined in the future by Podium Productions. But in the end it was a great race run by all.
