Well I finally replaced basically all my bushings and lowered my car about 1.5" and now I need to get it aligned. I will say just from driving around to check everything the car feels much tighter. But anyway what camber setting do people use for an AutoX setup, I know what I'm going to use for toe in/out etc. I've seen Pettit's specs. and heard they were actually pretty good. I'm planning on running either 255's or 275's v710s once my RA-1's from last year wear out. I'm thinking something like -1.5 front and -1 in the rear?? How does that sound?? I also may have a track day or two thrown in next year so I don't want so much it makes the car feel funny at higher speeds.

On 225/50/16 V710 rubber I've been running -2* of camber at all four corners, 1/8" rear toe in and 1/16" front toe out. I'd prefer to run even more front toe out but it makes the car darty on the street.

With stock 16" rims and springs (but 1.25" solid front swaybar) and Kumho V710, I max out front neg camber (2.2-2.3 deg - but sacrifices some caster) and have (1.25) camber in the rear. I use zero toe front and rear. Car can get a little loose on corner entry but I like this way.
I had tried equal front and rear negative camber but could not rotate the car well. Same for rear toe. Some toe in is helpful to put power down on corner exit but I ended up liking zero toe in the rear better. Much has to do with my front sway also. Big front sway bar helps putting power down but induces some transitional understeer (on corner entry or exit), which you can counteract with some more loose rear - not ideal perhaps but a good compromise if you have to use stock springs.
I have no track experience, but since you are planning on using the car on the track as well, I guess you may want to dial some rear toe in and more caster in the rear (basically, Damon's recommendations) to increase stability.

It all depends on the type of corners you have at each track. DamonB is bang on with the starting setting. I run a 1/16 toe in at the rear and a 1/16 toe out at the front. I go to a little more toe out on the front on my shorter tighter road courses. I start with 1.5 negative on all four corners then adjust from there. After the weekend I check my set up in the shop and find that it is not always the exact same but close. One corner could be negative 1 to up to 2.5. Tire pressure could be from 25lbs to 27.5lbs at each corner. Lots of things change the set up each weekend.

Race safe and have fun.

Thanks guys. I think I'm going to go with 1/16" toe out in the front, 1/16" in rear, -2.0* front, -1.7* rear and go from there. I have access to alignment tools, but I was told to get it aligned first by a pro. and then come by and see what it is set at and I could tweak it from there with his tools, and use it for future reference.

I run -2.3 camber all the way around, max caster, 1/8 toe out in front and 1/4 tow in in the rear.
