Right. I was going to mention this but you already see it. 5lbs off a bumper means more than 5 pounds off of a fender over a wheel, which means more than 5lbs off of a door in the middle of the car. This is F/R weight distribution anyhow.

Agreed that a roof is a big deal as well, though it's in the center of the car and changing its weight won't have much affect if any on F/R weight distribution, it is however up high which factors in strongly when "real life" handling is talked about. When you're looking at CG (center of gravity), keep in mind how high above the axles your mass is as well.
