Yeah, our rules at KARZ are fairly relaxed. We've even got some of the kids running on touring car foams, since it likely doesn't make much of a difference for them. Stu had some interesting rims he ordered in from somewhere, with a different offset. A few weeks back, Aaron was running some HPI X patterns on his M04.
As race coordinator, I'm completely cool with it, unless someone gains a massive, dominant advantage over everyone else because of the gear they're running. You, Stu, Josh, etc all did well not because of tires, but because you are all very good drivers.
So, until something momentous happens, KARZ is going to be relaxed about the tire rules. Everyone just has to remember to use the correct rubber if/when they run at CARCAR.
Hey, while I've got you here, Mike, it was M Grips you were running at all 4 corners, right? They seems to allow just enough slip on the carpet. Very nice.
