Agree with all of that - its about making a level playing field at the end of the day. The point of any rule set should be to stop those guys with deep pockets and/or access to machine tools, and the 'win at any cost' mentality, from dominating everyone else.

The way we went in Detroit (and at the one Danville event I was able to make it to) was to take the position that if your tank was stock, then it was ok - anyone else can go out and buy the same. Once you started to modify it tho, then you had to make sure that you were not gaining an advantage over the new guy with a stock tank in terms of speed etc.
