Front wheels rub. :(

That depends. That much caster without power steering can cause steering effort to be uncomfortably high, because you're actually lifting the weight of the car up in the front when you make a turn.
Yeah understand your point but it would be a surprise to me that anyone looking for a handling car would run manual steering. I have the borgeson power steering and a 13" wheel and it finally feels a little bit sporty. The issue you run into with wide tires and low or no positive caster is it wanders a lot. The caster makes it drive nice and straight which is the secret to most modern vehicles.

I have factory upper arms with moog offset bushings. I am going to ask the alignment shop to get as close to performance street driving on the skosh chart. ( Don't have it right on front of me) we'll see how it turns out.
Yeah, you should be able to get a couple of degrees I would imagine.
