I use a method laid out here with my $40 camber/caster tool. Put the front cam all the way out and the rear all the way in. Adjust the rear cam until you have about 1/2degree negative camber. This is the most positive caster that you can get out of the parts you have on the car.

Of course, this is AFTER setting the ride height and BEFORE setting the toe (I like about 1/16-1/8" toe-in).

If the car pulls with this setup, then you can check the caster and adjust accordingly, but I haven't had to alter from this setup. I also set the ride height to have about an inch between the LCA bumper and the frame (I use a better point on the LCA to make both sides even. I also check from the frame to the floor - same spot).
