Cobra (btw I like some of your setups, good job :) ), its not a special track.In the .ini file, you set the average temp to like -150 degrees or something like that and in the game you set it to realistic weather and it makes the temp real cold and the cars go a lot faster. I used to do this with online buddies all the time in N4 (arcade, but that was a while ago) and it was a BLAST!!
