Weight reduction

I have been looking into weight reduction for my car and found this:

It starts to get very interesting once you get past the first 24 or so pages of filler.
It has lots of good info I think.

Top gear gave me the idea when they gutted an old jag and removed 400lb and trimmed 1.2 seconds off the "not to 60"mph time and 5 seconds off the "not to 100"mph times. Then I figured I would look into it for fuel economy reasons too.

I am not looking for mods that kill drive ability. Such as when I pulled the back carpet with pad out of my car to clean and store it. After a week the added road noise lead me to put the carpet and pad back with a little added sound deading material.

The EPA had there own numbers which I figured were overly optimistic.
I am sure every one has herd the one about 100lb meaning the difference between 1mpg. I always found that one hard to believe. In my truck it took more like 500lb to make a 1mpg difference.
