I may be in the minority but I don't want 6 or 7 manufacturers. I'd be ok with adding one more, but as long as Chevy, Ford, and Toyota remain all in and don't cut back, what's really the point? It's not like the field can grown by a whole lot. This would basically become a low-end IMSA series if we get to 6 or 7.
Also, if they start track testing that soon, perhaps we might get some leaked photos? I just hope they don't rush it in order to meet the 2021 mark. Take the time to get it right. As long as the wait pays off, that's what truly matters.
