Please critique my autocross alignment - C6, stock tires
This is what I was thinking of for autocross, please tell me what you think:
FRONT:
Camber = -2.4*
Caster = As much positive as possible without sacrificing camber. (Keeping both sides equal)
Toe = Toe OUT, 1/8 inch
REAR:
Camber = -1.5*
Toe = Toe IN, 1/8 inch
The car will not be driven on the street with this alignment. Also I am on street tires for now (Firestone Firehawk Wide Ovals), so is that fine with this alignment?

You have a good starting point. Personal preference will dictate if any changes are necessary.
Some things to think about and try if you want:
1. More rear toe will make the car more stable under power on corner exit.
2. Less rear camber will help the car rotate on corner entry allowing you to get to the power faster. It will also let you put more power down in a straight line. The down side is that the car will be a little less stable in high speed manuvers.
Try different things to see what you like. I have probably run 40 different alignments in the last two years. My preferences have changes as I got more comfortable with the car. The front bar, shocks, and the types of courses you run on will also factor in.

It would be tough to get that much camber out of the stock front suspension. The car will be tail happy with anything less than 1/8" rear toe in. Thats what I run on my car with street tires and I can hang the rear end out pretty controllably with throttle to get the car to pivot (1.1 neg camber rear).

I can get 1.9-2* neg up front if I back down the caster a bit (~6.5-7*), but that seems to be about max. It works well on the street with 0 toe in. I run 1.1-1,2 rear with 1/8 toe in. Have great turn in for autocross, can pivot the car with throttle, and have excellent tire wear (running stret tires). Unless you're running race rubber or are serious about autoXing, I think you'll be happy with a similar compromise set up.
