As you noticed, Tolerance is as big as a barn door.
If you stick to those SPEC #'s, (Not just "Within Tolerance") you should be Fine.
Here's what I would change...
You want ALL the Negative Front camber that you can get, to the extent that both sides match.
(You'll need lower springs and/or a set of camber plates to change that, though).
I would set the rear toe closer to 0.
Rear camber is OK if you go with spec, but for Auto-X, I'd try to get more negative out of the front than the rear.
Camber front: -2°
Camber rear: -1.7°
Caster front: 3.75
Toe front: 1/16 out each side for a total front toe out of 1/8
Toe rear: 0 total
This is an awesome set-up, the turn-in is sooooooooooo much better with that spec
The only trick is getting those camber #'s nice and even without investing in camber bolts and plates.
If you have those, those settings look Great for a car that sees regular street duty in addition to Track and Auto-X.
