Very good set of tracks that are quite fun to race on. I know you've addressed this with another review, but the AI is a bit wonky at some tracks, like they will completely ignore track limits at like Daytona and Talladega and try to pass you wherever. Overall, though, I think this a very nice mod, especially paired with the CART Extreme mod.
For those of you with issues with the NASCAR mods at Talladega or Daytona, I noticed the will load fine fine if you make 1 change the gdb file.
Change this:
RestrictorPlate = True
To this:
RestrictorPlate = False
