sup every one i just purchased a 1993 325i w/ 5 spd transmission Us model. Im ready to start cutting on it. My major question is what weight reduction can be done without any major discomfort?? I would like to keep the interior and a/c, but my plans do include gtr hood, m body package, LWT spoiler, and side exit exhaust. Anymore advice on these modifications and any suggestions will be appreciated. thnx ian
