the rearrangement of groupings to get IT, prod, and GTL all in separate groups to allow for IT triple dipping would be very difficult in some places as usually 2 of the 3 are run together.

overall I think IT in GT is rather silly, and while I don't object on the grounds of danger I'd suggest it might be better to let the prod or ST cars run as GT in their current prep. IT in ST and P, P and/or ST in GT, GT in P... double dipping for everyone!

then we can consolidate everything to 2 categories of stock tubs (T, IT, ST) and flared fenders (P, GT) and call it a day.
