Don't forget the ABS! That sh*t sucks anyway. You can also ditch the stereo and speakers, get a fiberglass, aluminum, or CF hood, replace the sunroof with a lexan/aluminum/CF panel, replace the power antenna with a fixed one, ditch the foglights, ditch the spoiler, replace hood latch and hinges with 4 pins, gut rear door beams (assuming you have no rear passengers/seats), convert electric windows to manual, replace rear door glass with plexiglass/lexan, get an aluminum X-fer case, a lightened flywheel (which has other benefits), ditch the charcoal canister and other emissions BS... hmm. That's all that I can think of off the top of my head. Ooh, maybe some tubular or aluminum lower control arms, if you can find them.
