I can tell you what i run....
And it seems to work okay.
Front toe 1/8" in
Rear toe 1/8" in
Ride height is pretty low, but I do run the front 1/4" higher than rear.
For camber, I just take what I get. It is about 1 1/2* - 2* negative front, about 2 1/2* rear.
Primarily street driven with an occasional autocross.
I used to run 1/16" toe in on the front, but the car liked to hunt too much on the freeway. That little toe may work if you have fairly smooth freeways, but in Oregon, the interstate highways are rutted pretty heavily. Fortunately, an X is narrow enough that I can straddle the ruts and run on fairly smooth road.
Ciao,
