Take out all the weight you can. If you want you can take the backseat out and try and keep both front seats as far forward as possible. Find a real desolate curvy road to practice on, don't take it to hard just enough to get a feel for turns and how to pitch it into the next. I live on one of the curviest highways in Iowa, If you brake going into turns and then accelerate a tad through them, it will help to make the turn faster and cleaner. Your front wheels will help pull you around and as soon as you feel your ass end get light/loose let off. Keep your car in 3rd the whole time so it doesn't go into overdrive. When you start the race, do a quick squeel of the tires to get all of the dirt off of them.
