Alignment question?

So im going tech school right now and im in an undercar class and thinking of doing a "race" alignment on my car. Are there any rules against this? Im in ST2 g-stock. also if anyone has any experience with doing these types of alignments any suggestions would be appreciated ive never done an alignment before much less playing with differnt camber, caster, and tow angles.

Class questions

Well first off let me introduce myself, my names josh and i moved here from MN for school a couple months ago, ive been to the last 2 events, alot of you probably saw my blue and green taped 07 Si at the september event ( its my first new car and i didnt want to get it dirty give me a break ) anyway ive been competing in st2 and was wondering what kind of modifications are alowed in this class, i dont want to get to crazy just some struts and springs, im geting the factory 18" HFP wheels with some better tires ( what are the limits for street tires) and i need to talk to the dealer about warenty issues but id like the hondata reflash too ( about 25 extra wheel ponies and gets rid of drive by wire lag, and the rev hang) but that also requires an intake and exhaust for it to work best. Any help or suggestions would be great. this is my first year autoxing, i started last spring with the MNautox guys. so im still kinda new at all this.
