Hey, I have a 1990 Acura Integra 4 door sedan. I was wondering, what are some ways I can lighten it up a bit. I already took out the back seats but they didn't weigh much really. I also removed the carpeting, and spare tire.
As tisguy said, it depends on how far you want to go with it.
As TegSox said, you can probably save 50-100lbs just in removing the stuff he mentioned.
If you want to go all out (like me and a few others), there's A/C, P/S, heater core, blower motor, dash vents, interior paneling (I kept the front half but everything else is gone), and even go as far as cutting certian parts of the interior subframe out (as long as you have proper re-enforcements in other ways like a cage or something), get rid of misc. brackets and clips, and replacing OE panels with lighter carbon fiber or possibly fiberglass, lighter wheels, get rid of the glass and put in some FAL windows, the list goes on and on...depends on how far you want to go.
Yeah those are really good ideas, I am planning on going pretty light with it. So I am probably going to start doing some of the ideas you guys posted soon. I'll probably start with the sound deadening material, which I heard was a bitch but one of my buddies told me I can use dry ice and that it makes removing the stuff far easier. but I'm gonna have to do some research on that before I go and try it out.
