Anyone know if weight reduction is worth the trouble. Im not going to the track, or hardcore, or anything. Just always wanna be a little faster. I have a 30lb subwoofer (just downgraded from my old 60lb) in the hatch, and am trying to comprimise. Anything I can ditch, besides the sub, its not going. Mabye the spare tire or something. They're a b***h anyways. Or is it even worth it?
