I figured it might be useful to get an official weight thread going (since I will be doing it in a spreadsheet for myself anyways...). I picked up a set of Intercomp corner scales (1500b capacity per pad) that I have been wanting for quite some time. I usually like to get a baseline weight before I get started modding as I like to keep everything tracked on a spreadsheet with reducing weight in mind for every part I choose (I weight parts on a calibrated 75lb postage scale). I like the challenge of saving weight without sacrificing too much for daily driving. For some people maybe it is for the track, for me I like to improve my braking, acceleration, and fuel economy for as little $$ as possible. Doesn't matter how minuscule each item I save weight on, I enjoy the challenge.
I have two F80s at my immediate disposal, but if I can have some of the other local metro-Atlanta folks swing by I could get even more data about the cars' weights with various options as well as get some F82 and F83 on the scales. But for now this is a start.
If you have any weights you'd like to add that have been weighed on a package or postal scale for parts that I haven't mentioned, please respond and I'll add them. I just ask that we avoid the bathroom scales... I will be adding more weights myself as I have time.
