Boxster weights

you got a lot of the low hanging fruit.

you mentioned carpets; the sound deadening around the engine is HUGE (35lb+); it's 8" thick in some parts.

cat bypass pipes save 20lb over the OEM cat pipes.

racing muffler saves 45lb over OEM

(precision chassis works sells a BSR legal header back exhaust system that weights only 17lbs. the OEM is close to 90lb)

AC was much lighter than i thought it would be. 15lb for the compressor, 5lb each for the condensers & 4lb for the tubing (29lb total).

you mentioned the convertible top & all its 'stuff'. did you get the transmissions out? they're HEAVY.

obviously speakers & stereo stuff

side airbags = 5lb each
passenber airbag = 10lb
steering wheel / airbag = 12lb (if you install a racing wheel instead)

it's a slippery slope.....

Funny, the more I do, the more I forget that I've done! I've taken care of the exhaust: headers, Fabspeed bypass pipes, and a Borla muffler. I've also removed all of the stock sound deadener around the engine. The top transmissions and all hardware is gone, as are the clamshell linkages. It's now held in place with rubber tie-downs. I've also removed the rear trunk latch and cable, replacing that with aluminum pins. A CF or fiberglass hood may be in the future..
I plan to ditch the door & passenger airbags this winter, as soon as I can get a little quality time with a PST-II. The AC is also on the chopping block. If the PST-II has a disable feature for the secondary air injection, all of that will be gone as well.
I've heard that the rubberized undercoating is pretty heavy. Any thoughts on that?

My personal "rule" is that I can drive the car to and from autocrosses. That means keeping a VA inspection sticker. The folks I take it to aren't worried about the exhaust, but I can't have airbag lights on, and can't replace the steering wheel. I'm wondering what I could lose from the doors, but I think I'm stuck with the power windows, as I need some function there.

My engine bay insulation is starting peel off at the top opening. Is the same material that you pulled out? I am surprised that this came to forty pounds!!! Can get it all out with the engine in? Did you notice a big change in noise? I sometimes run with no storage box and no engine cover insulation. You hear everything....vibrating and buzzing

NO! that stuff is pretty light. the material i'm talking about goes around the sides of the engine hatch, on top of the hatch, and behind the seats. it's VERY thick; it's made of the same stuff the engine hatch insulation is made of. extremely dense & heavy.
