When I weigh my 2019 GT3T, I’ll post here too.

Had my car at Alekshop in Fremont yesterday for an alignment. The car weighed in at 3208lbs. Anti-Gravity Battery, Dundon Headers, full tank of gas and BBI Harness Bar.

991.2 GT3 RS: DDW Partners weighed a bone stock 991.2 GT3 RS WP+PCCB, full tank of gas with the extended size tank at 3,207 lbs on BBS FI-R wheels.
On stock wheels: 3,230 lbs. However, remove WP, add steel brakes and sofa seats (18-way) and this same car would be ~95 lbs heavier at 3,325 lbs. On a popular rear half cage, steel brakes, bucket seats it gets close to 3,370 lbs. Add a fire extinguisher, sub-belt mounts, camera equipment and it can get close to 3,400 lbs.
991.2 GT3 weighed 3,318 lbs by C&D, but that car had sofas, standard brakes and the small fuel tank. Motor Trend weighed a 6-speed GT3 with standard seats and steel brakes at 3,270 lbs, add PDK and it gets to 3307 lbs.
On equal equipment, the 991.2 GT3 PDK is 10Kg (22 lbs) lighter than the 991.2 GT3RS. Porsche published weighs are misleading, but we can Thank the car magazines that put the cars on the scales and get accurate readings (C&D, R&T, MotorTrend) for U.S. version cars.
Manual vs. PDK is 37 lbs.
Radio Delete (from base radio) is -17 lbs
A/C Delete is -26 lbs
Lots of low hanging fruits for weight reduction: Battery, wheels on 19" or Mg, side muffler deletes, then items to reduce weight become small on weight saving or a little expensive.
For the GT2RS (which DDW Partners weighed as well with 1/2 tank of fuel), adjusted to a full tank of fuel: 3,398 lbs. This is a car with standard wheels, PCCB (std) and WP. C&D weighed another 991 GT2RS at 3,376 lbs, but this one had the 25 lbs lighter Mg wheels, so on std wheels this Green C&D GT2RS would be at 3,401 lbs. Replace the PCCB with Girodisc steel rotors, add a popular rear cage, 2 sets of harnesses, sub belt bar, fire bottle on a car without WP and now the scale will read around 3,550 lbs.
Fuel load can vary weight readings by 148 lbs, so the best way to do this and get close to accurate results is to put the car on the scales on a full tank.

Does anyone have actual corner balancing numbers for their cars?
I was told mine needed corner balancing, but the way it was presented didn’t make much sense to me. I understand that you want as little cross difference as possible, but are there acceptable tolerances?
Winter tires on at the moment, so won’t be on a track in the immediate.

Sure there is an acceptable tolerance. YOU decide what it is for YOUR car. Plenty of people are fine with the car off the showroom floor, and might not ever notice a difference. I mean it's not like your car is going to be two hundred pounds out of whack off the assembly line. Some fanatics will start moving components of the car trying to get it as close as possible. Personally I say adjust the coil perches a little bit to get it as close as you reasonably can that way, and call it good.
