Yes, I'm a rule Nazi. Not going to apologize for that. But I'm baffled at how bodies like the Riley Prototype are allowed because "that's not what is winning" and this one is no different.

And please don't mistake my position. I am in the camp that purpose built racing cars should be excluded and the rules should tightened up and made black and white. I predicted more issues like this. My main reason being what if something just like the Riley prototype comes out, (it's legal, the precedent is set) and it is actually much, much, much better than everything else. USGT will become a one body class like WGT.

I believe your original intention is sound. GT cars. Just make the rule tighter.
