I can't find my notes at the moment, but the basic theory is that camber plate changes also change toe, fortunately for us in the right direction.

By setting toe out a bit at your "track" camber settings, moving them 1 degree out to your street setting, the tow changes to slightly in which is fine if not actually good for the street.
I agree that the theory is pretty beneficial. The drawback, IMO, is that the toe changes a little too drastically. I'd like to run 0 toe on the street, and just a tiny, tiny bit of toe out at the track.

The reality is, if you're tipping over the camber say and additional -1 to -2 deg, you end up needing to run toe-in on the street, and quite a bit of toe-out at the track. I too can't remember the actual numbers for the toe change, but it's certainly too much toe out than I like from a handling perspective. Maybe for autocross that much toe-out is okay, but I dislike the excessive tramlining under braking and wear at the race track. 'Course, at the race track on r-comps, I would need to go from like -1.5 deg to -4.0 deg anyway which is too much to attempt to setup predicted toe change around anyway.

Plus, I'm lazy. So I just set the camber to max neg and the toe to 0 on the WRX and just live with the crappy alignment on the street since the car rarely gets driven anyway.
