There has been TONS of discussion and information on this, and I don't think many will agree with you. The BIG CHANGE is due to radial tires, which "like" different setup than the old bias ply tires.
Well, argue if you will. Radial tires or bias tires make a difference in handling, not alignment. Alignment is geometry, nothing more. It is the angles that apply the tire to the road. I have worked in automotive service most of my life. I'm not making observations based on conjecture. Can you change the alignment to do different things? Of course you can. Will it lead to excess or uneven tire wear? Yes it will. I won't argue that you can change angles to help steering or tracking, but what you gain in one place you lose in another. My Dart is aligned to factory specs and I have no performance issues whatsoever. My tires wear smoothly and evenly. The only excess tire wear I have is in the rear wheels, and that has nothing to do with alignment and everything to do with power.
