If you are looking at getting started Autocrossing just come out. You dont need the "Hot" tire when you are just getting started. It is all about car control and its nothing you can learn on the streets. So just come on out squeel some tires and have some fun.
I have a 99 Lude so that generally would put me in DSP however because of my suspension mods (Springs/Shocks/Braces) and engine mods (VAFC, CAI, Apexi WS) I think that would put me in ST and since I am in the D group I would be DST right? I guess what I am getting at is if I am going to get bumped up from the SP class I might as well modify my car as much as possible within that class to make my car as competitive as I can so that the limitation is the driver and not the car.... if you get my logic.
