One more thing to put in the mix... I called AC and they said that the spec for the AC lift as far as the distance from the bump stop and the pad on the a-arm should be no less than 1/2" (I wonder why SLR's spec says no less than 3/4"?) and you will be able to get the camber and caster adjustment into factory spec. Again, I have 2" of space.
AC also said that if they hace any problems to call and they will explane how to get it into spec... I'll be taking it in on saterday afternoon to allign it.

I'll let you know...
