Great track. I'm not sure what change you made, but it works really well. A few years back I had this other version of Montreal from **************** I think, but that version isn't as good. It lacked many curbstones and brake markers, but this version has those covered. It drives so much better.
The only thing that could still be improved is the AI, I noticed they may hit the wall when exiting the last turn sometimes. Otherwise great stuff.
