The A/C saps a little power all of the time because you're still spinning a pulley. If you were to remove the compressor and all of the associated plumbing I would expect to see over 50 pounds saved. Add a new (usually much lighter) aftermarket exhaust, take out the spare tire and jack, remove a few other things and maybe you can't get the portly STi below 3000 pounds
