Yeah I do drive at least 25k miles a year, so the increased gas mileage from lowering is nice. I'm really torn on this, I really like both looks. I think I'll wait until this winter and see how it does in the snow, that will be the deciding factor. I definitely won't be doing a 6" lift, that's too much for me. I guess you could say it would get a 5.25" lift from the current stance... Since I drive so much, I will probably stick with stock size tires, maybe a little wider... My Coopers are actually wearing pretty well. I have over 20k miles on them and they have at least 25-30k left. And that's with heavy use of the skinny pedal. A normal person could probably get 75k miles out of them.
