Wow, you took out 200 lbs, and it cost nothing?! What did you do? I think I took out about 100 lbs off my '89 CRX Si by taking out most of the plastic interior panels, the carpets, some of the tar (still working on it at a slow pace). Is there other stuff you can do without spending $$$ or having a lot of mechanical skills?

I'd also like to remove the A/C and motorized sunroof, but I'm not sure how big a deal that is.

So far, weight reduction also happens to be my most effective mod, but that's only because it's the only mod I have so far.

I'm waiting on a set of TE-37's, but that doesn't count since it's not on my car yet.
