I know that weighing your car with a light load of fuel makes for a flashier number, but you should really weigh with a full tank to compare with the stock cars as tested by, say Car and Driver. The magazine measured a stock 991.2 T with the manual transmission at 3221 pounds with a full tank. The article probably describes what options it had.
Moreover, when you approximate an eighth of a tank or a quarter of tank you could be off by a gallon or two. If you always weigh with a full tank, you eliminate that source of error. It makes it easier to accurately tabulate smaller weight savings.
Porsche's claimed weight for a T, presumably with zero options, was 1425 kg, or 3142 lbs. But that is a DIN empty weight, which is with 90 percent of fuel capacity. So a proper full tank measurement would add an additional 6.4 liters, or 1.79 gallons of fuel. That weighs about 11 lbs, bringing the curb weight up to 3152 lbs.

I’ll see if I can find a reference later, but that weight is actually the lowest spec weight, not just zero option, so the car was optioned with LWBS (~120lbs lighter than 18 ways), PCCB, and then didn’t have any options that would add weight (rear steer, leather, sun/pano roof, etc.).

The C&D test of 2 991.2 Carrera Ts is a good reference point. The manual transmission car was fitted with buckets, RAS, and nothing else. As you stated, C&D's published weight was 3221lbs with a full tank of fuel. Their PDK test car was also minimally optioned though equipped with the standard/4-way sport seats plus and also had RAS. Weight as published by C&D with a full tank was 3290lbs, a difference of 69lbs accounted for by PDK, standard 4-way seats, and rear seats with seat belts. Important factors to note are that all 991.2 Carrera T's sold in North America came equipped with PCM and rear seat delete was only available (and mandatory) on cars optioned with full buckets. Cars with 4 & 18-way seats were equipped with rear seats in North America from every indication I've seen.

im also working to get as much weight on front tires as I can with competition fuel load so need to weigh corners with me and fuel load I usually run with to see how I’m doing in keeping balance of car.
….another funny note. I haven’t had a full tank of fuel in this car since I took delivery 4 years ago. 😂

^ Just love the focus of this project.
I am sure I missed it somewhere, but what battery are you running given your goals of extreme weight reduction while keeping weight on the front wheels?

I’ve focused like crazy on rear of the car. I don’t run exhaust tips, all engine dressing gone, some heat shields removed, lower part of bumper along with steel bracket deleted, plastic runners on rear lid pulled off, sound symposer deleted, AC compressor removed, rear bumper bar removed, exhaust system lightened with titanium pieces, all insulation behind b pillars gone, titanium studs , rear lid struts removed, few more things to get weight out of rear. Then worked with shop that did my alignment to do corner weights to shift as much weight to front as possible.
