Chad I autocrossed many a day in 105 heat
changing tires on and off the car before and after
I used to run against a Doctor who had AC in his turbo
car... I would go over and he would barely roll the window
down.. ac blasting... classical music going... I told him
that it was cheating.. he just laughed and rolled the window
back up.. had some fun times running against him
Now if it gets too damned hot I just roll into my f250
and crank up the AC for a few minutes
