Based on available stats and doing some math:
AM&S/SA weighed a well optioned DCT F80 at 3582lb (1625kg) with a 52.1/47.9 distribution. The
official specs for the G80C are 3890lb with a 53.1/46.9 distribution. Doing the math the F80 carries 1866lb on the front axle while the G8X 2066lb. So the G8X carries 200 of its 308 added lbs on the front axle.

But even these added dimensions would not add up to 350lbs gain.
What else has become so heavy ? no carbon propshaft anymore maybe ? Bulletproof glass or armored plating ?
You can talk all the numbers you want but in the end -for a track oriented car- more weight will require wider tires, bigger brakes, resulting in more weight again... and once you step over the line of adhesion, it takes much more energy to dissipate before you gain grip again. You need a lot of extra grip to compensate for 200kg at 1.5G taking a corner.

300~350lb range comes from the different G8X official specs from around the world compared to weighed values of the F8X. I think the weight gains comes from the increase in size, added luxury features as well as, and very importantly so, very little weight reduction effort over the G2X.
There's always been some sort of weight reduction effort on ///M cars to offset the weight of the added go-fast goodies. However, particular effort was made on the F8X to reduce weight over the F3X baseline, where the F8X ended up even weighing less than the top series F3X.
