I'm going to be racing on a 1/3 mile dirt track in central Wisconsin at the end of the month. It's for an eve of destruction event and I'll be bringing a 2002 grand prix gt. I was just wondering if you would help me out a little on how to set up the car. I have never raced dirt before. I am wondering things like what size tires and air pressure you run, do you mess with suspension at all and you mentioned taking out the front seat bar which I'm assuming helps loosen the car up. Any help would be appreciated. Thanks, Josh
