Guys,
I did a quick search on this and didn't find anything. I sold my Boxster earlier this year and am considering the purchase of an early 90s C2 that I would use primarily as a track car. I owned a C4 years ago so I am familiar with the car.
My question - what kind of track weight should I expect, assuming that I remove the A/C, seats, insulation, etc. and add a roll bar?
If you provide a weight, can you include additional info as to what exactly you gutted from the car?

Speaking from the been there done that perspective:
Remove the easy stuff like you indicate: 2800 lbs
Gut it completely: 2450 lbs
Gut it again and cut out every bit that's not essential, rewire, and go nuts trying to remove weight: 2150 lbs
By remove the easy stuff I mean a normal interior strip, removal of AC and removal of all the easy to remove non-essential parts. Remove the interior comfort stuff (sound dampening, carpet, stock seats, radio, etc). Remove the easy to remove HVAC (compressor, AC pipes, rear blower, etc).
The next step is to substantially dismantle the car to get to harder to remove stuff (all air distribution and climate control parts, etc), removal of bumpers, gut the doors completely, etc.
If you strip it back to the tub, remove all factory electric that's no longer necessary (eg all but the engine harness) and rewire, remove the dash, the fuel filler at the fender, the hinges for the hood, cut off every bracket that's not required, swap a fiberglass roof for steel, etc. you can get pretty low weight. Geoffrey still has many stock components and is at a weigh similar to mine, so it's variable regarding what you remove or retain but to get really low weight is a major effort.

Tom's nailed it. I got RSA #1 down close to that error-in-the-rulebook 2760 lbs on a factory non-a/c car. And it was honestly a car that met the letter of the stock class rules! But RSA #2 at ~3000 lbs works fine for a car still having a license plate. I wouldn't go overboard in compromising the car's usefulness as a street car. For DE events, what does a second a lap really matter? My yellow car is lightened up, and believe me it's horrible. But that's what the previous owner did........

My 93 RSA (no sun roof) weighed 2750 with half a tank of gas. It has air conditioning, a carbon fiber hood, Recaro PP's, and a DAS roll bar.

Currently mine is 2893lb (1315kg) with a/c, leccy windows and roof, pole positions, rs interior and 3/4 tank of fuel, but now rear wiper, rear seats sound deadening etc.
I know of another similar to mine but no a/c or sunroof, but with a full cage and it is only 5kg lighter.

My car got weighed recently at an autocross:
2790lbs
Pole positions, RS clone carpet (all sound deadening still in place), no radio or speakers, no rear seats, no trunk carpet, spare tire in place, no tools, 1/2 tank of gas, FM-10 17". A/C, sunroof, airbags all still in there.
I was pleasantly surprised. The general consensus at the event was that the scales were accurate.
