See what happens when you ask questions on a real forum? Not FocalJet LOL. I noticed that nobody could really help you out over there. Let us know when you get your wheel/tire setup on the car and how you make out with it. Have you run the car at all with power level in your sig?
BTW the best setup for the hoosiers is about 10-14psi and launching the car at 5-6k. Any less rpm and you will probably bog and any more and it will spin.
