I didn't read all the posts but read the rules and I LOVE the idea, I've got a small wallet but I've got alot of parts and alot of knowledge and I think I could make my car competitive in a class with these rules. I basically have to build a tube rear clip on my car now anyways and move my suspension mounting points to get my wheelbase to line up again. I think it would be an awesome class to watch, especially if they're faster than the Thundercars.

i say they do wheel barrow races with guys riding in them with helmuts on! that would be a funny intermission show!

Either that or shopping cart races! that would be great! have a pro 4 wheel shopping cart division! The winner of the race gets a trophy with a little shopping cart on it and a gift certificate to go get groceries!!! lol
