Just updating for clarity. Apparently DIN has changed the way they weigh cars as of this year, so as of now Porsche is quoting weight in the base spec, not the spec with the lightest options. This...

Lightweight buckets 24 lbs
Smaller tank 20+ (on paper per din)
PCCB brakes were less because the stock steel brakes were relatively...

The idea that they developed and homologated a bespoke engine yet couldn’t afford to beef up the transmission to take advantage of it is amusing to me.

Hmm, good info (and good change on DIN's part, Porsche has been using that loophole to the max for years). I'm waiting for the options list- usually they make the extended range tank optional, etc,...

1420 kg/ 3130 lbs.

Not clear if that's all real or if they eliminated some weight saving options like the smaller fuel tank.

I’d like to hear how you and others suggesting the GT4 has a “better chassis” than the GT3 are using the car. My suspicion, unsupported by data, is that your use-case is different than mine.
