Hey guys! newbie at the track ran 15.7 @ 91mph with a '60 of 2.3 sec. '95 gt o/r x-pipe, drag radials and short throw shifter. I've been studying my slips I know I need to work on my launch, shifting points and play with tire pressure. It was kinda of hot so I had my windows rolled down will that slow the car down? My question to you guys is do you race with your windows rolled up or down?
