alignment specs
 
I have a 71 camaro that I am finishing up. I am looking for alignment specs that would be suited for auto-crossing and street driving. I am not concerned about tire wear, just want better performance. Thanks for the info, JS.

As much positive caster as you can get in without hitting the fenders, in this case id shoot for 5-7 degrees (PTFB is one of the only companys that makes arms that can accomplish this). 1/16th of toe in, and a half a degree of negative camber.

if your not worried about tire wear than i would look at a little lower caster # and more neg camber -.75 to -1 or even more, and the toe i would run at 1/16 to 1/8 toe out.

So I should have gone more in depth I guess. There is no street and track alignment, but there are compromises that are good for both.

With the stock control arms you should be able to get about 2 degrees of positive caster, in this case you want as much as you can get. There is no such thing as too much positive caster, If you can get 10-15 degrees then get it.

Toe is the adjustment that will wipe your tires out the quickest. On a street car 1/16 to 1/8th toe in makes your car "track" nice. On a track car 1/8th toe out will cause better traction on corner entry. For a track car that spends most of its time on the street then no toe "0 degrees" is a good balance.

For camber, on a street car that sees cone days I would run .5, that's why I recommended it, 1 to 1.25 degrees negative might be better though. The limiting factor on this will be your suspension condition, and how straight your bushings, ball joints, and arms are. This is where the alignment tech comes into play, as he has to hit all these numbers while maintaining proper cross caster and cross camber settings, and not shimming the arms into oblivion.

Clear as mud right?

I would also go for as much caster as possible.
0-toe is a good balance, 1/16th in will make car easy to drive, 1/16th to 1/8th out will make car turn in nicely, but will be more work to drive.
camber, I run as much as -1.5 on my development car on the street with no major wear, however my car only sees 1-2k miles on the street per yr.

caster-as much as possible
camber- at least -1.0 if not 1.25
toe- 0
