Four right now. I stopped to level my three spares before I move on to the Miata 4-Hour and beyond.
G.Pace is my level 26 workhorse (my B-Spec is level 27, overall).
J.Day, S.Chiba, and P.Townsend have been getting power-leveled with an FGT through Dream Car Championship until they are each at least 20.
I'm looking forward to the longer races.
