My settings, Warning, for extreme setup only!!
Front camber: -2 degrees
Front caster: +5.5 degrees (alk & upper plates required)
Front toe: I run ~0.25 toe in on the street and ~0.25 toe out at autocrosses. The little toe in on the street helps keep the car from going all over the road.
Rear camber: -1 degree (provided by the Eibach's)
Rear toe: 0
Like I said, my settings are pretty extreme, but I'm happy with the way the car handles, and I really don't get very bad tire wear, except when I'm running the toe out.
