Currently in GT Sport, Gr. 2 is a Super GT GT500 class. While the first obvious expansion of Gr. 2 would be to add in DTM cars, what about also including IMSA DPi cars like the Acura ARX-05, Cadillac DPi-V.R, and Mazda RT24-P? While those are prototype cars compared to Super GT/DTM Touring cars, the modern Super GT cars make more power while the DPi cars are lighter by several hundred pounds, so I like they could be BoP-ed the effectively. It would come down to if the aerodynamics and vehicle dynamics of the cars are drastically different or not, which I don't know about.
