Depends on where you plan on driving the car. Often it seems people setup with a front -neg camber bias for the track and a rear -neg camber bias for autocross.

That's funny. I had a icehawk alignment before and it more understeer in lower speed tight turns. With front camber bias this is gone. The only problem I have now is that at highway speeds it feels like it will change lanes if I blink wrong and the steering is very light even with no PS. Not sure if I will add toe in at the front or add caster.

only at -1.7F and -2.7R, but I agree, the camber in the rear is very nice.

If your car is twitchy on the freeway its due to toe out or no toe at all, camber shouldent afect that to much. for the street 1/16 to 1/8 toe in is better for the track the exact oposit will give you faster turn in and steering responce in general.

Maybe I am confused, but Urban's "track" setup is pretty close to what I use for autocross

-2.4 to -2.8 degrees camber front
-2 degrees camber rear
max caster
1/16 toe out front
0 toe rear

that is track setup though... my specs are in that "specs thread" if interested
and Paul's "Autocross" setup sounds more like what I hear the track guys run.

auto-xing last week with -2.5 degrees in the rear i had no grip out of turns on my Nitto 225/45/15 NT-01s. Car was last aligned before turbo.

Just had it aligned Tuesday to the following specs.
FRONT
-1.5 camber
4.0 caster (manual rack)
-1/8 total toe

REAR
-1.0
1/16 total

Will find out this Sunday how it does.

Btw, during the morning session it was pouring and the car was ******* awesome. Of course I was a bit more conservative with the throttle. In the dry when I'd drop the hammer it just couldn't hold.

Just for the record.

Koni 2812's
750#/400# springs
Keizer 15x10 6" backspace
Hoosier A6 275/35/15
4.30 Torsen rear end swap
All measures with driver in car.

Alignment settings
Front
Camber -2.9/-2.9
Caster 6.3/6.2 ( love those offset bushings)
Toe -0.17 degrees ( that should be a little more than 1/8 total toe out)
Rear
Camber -2.2/-2.2
Toe 0.06 (slightly less than a 16th toe in)
Thrust angle -0.04

Daily driven -1 camber and 1/16-1/8 in, in the front, -1.5 1/16-1/8th out in the rear drives nice with no tire wear isues or jumpieness at all. But this is just for daily street driver.

Interesting numbers, Chris. My current setup-

Front:
Camber -1.5
Caster +5.2, +5.7 (couldn't quite get them even)
Toe 0

Rear:
Camber -2
Toe 0

I'm running 318/233 springs, FCM-revalved Bilsteins, a 7/8" front bar, no rear bar. Tires are RE-01R on 15x7. This is 80% daily driver, 20% autocrosser and canyon carver.

The setup is quite neutral and even-tempered. On trailing throttle you get just a touch of understeer, with the application of power very nicely shifting the vehicle into oversteer. Once the rear tires break loose, you can recover the car almost instantly simply by letting off the throttle.
