Not that they will be changing the rules at this point, but if they had known it was going to be so successful, they could have said that only 10 year old chassis are legal or something like that. As I understand it, that was the original goal was to get a class where you could use your old stuff rather than have it sit around. That being said, I think Myron Kinnard did pretty well on a national level with a TC4 not too long ago.
