newbie here, but i saw this thread, so i had to register and post.
one of the cheapest and seemingly obvious ways to shave pounds off is one of the most overlooked. my buddy was obsessive about reducing the weight of his car, stripping almost everything down to bare bones. he asked me if there was anything else that he could do to reduce the weight for his races. i told him to lose 50 pounds. he is an exceedingly overweight person. if you are serious about racing, than your physique should definitely be an issue. granted it takes a little more time to acheive than just throwing the back seat out, but as we all know, every ounce counts. when was the last time you've seen a fat jockey riding a horse in the kentucky derby?

well, why should car racing be any different? i bet most of the people who read this could stand to lose a few pounds, and guess what? this takes pounds off of the total weight! i just thought this was funny, because he cared so much about stripping out wiring, and carpet, and nuts and bolts, and he could have just dropped a couple lbs, and kept it all in his car! think of it as a personal weight reduction.
