I don't see the point in jumbling so ITR and STU aren't in the same group. ITR will have what, maybe 8 cars at most? How many of them would be interested in double dipping into STU if they could? One, maybe two? Not worth it. Really, I'd be surprised if that Group 1 has any more than 15 cars in it, unless there's something I don't know about a bunch of ITR and/or STU cars planning on showing up.

I think this will be the first time GTA has ever ran at Mid Ohio. Hopefully a bunch of those guys will come up, because that'll be cool.
