I'm not clear on all the differences either. Surely the tub is the same. Must be some things other than the obvious aero stuff that are different. There was a reference in the NBC coverage that there are even different uprights for the speedway cars. Surprising to me as even in the CART era when the rules were much more open, we ran the same uprights for all events. Wonder if Dallara has a website with a parts list.
