+1 on ds2500 if you do decide to do that, works great on the street for me. Just be careful before it's bedded in. Stock brakes worked fine for me last year, but you will want to bleed often and/or upgrade fluid. Realizing the fluid boiled on you in the middle of a run is interesting.

I did my first 3-4 events on stock size street tires then went to 245/40 re71rs on a 9" width rim because I wanted to see where I stacked up relative to others in the class. AX is fun either way, you just get different things out of it. If you are going with sticky tires, I would add some negative camber or you are just going to be using the outer edge all the time.
