Last time I checked, I don't rub, I don't have crazy camber, yet I do have proper suspension movement. (Disregarding the fact that my car is probably too low to have 100% proper geometry.)
+20, 9.5" wheel, 265/35 tire, -1.5 rear camber.
Like you said, you just need to "work" the fenders to get proper fitment.
