hehe bill nailed everything I can think of..
but I kind of agree with Aaron.. taking out all the interior stuff that weighs very little isn't worth it IMO but then again, you ARE going all out for performance so I guess every lb counts :thumbsup
Anyway yeah.. cf or fiberglass body panels will help alot methinks..

Door skins are f'in heavy.. I'd estimate around 60 lbs?
Hatch is pretty heavy too..

I know there's a lexon (sp) replacement for the hatch or hatch glass or something.. but not sure about door skins

btw this post should be archived in things we've seen before when its done :thumbsup
