The guy in this vid seems to calculate that the car will weigh 1440kg in Weissach trim but I think that is wrong.

Porsche said 1470kg is the DIN weight for an unoptioned car so add in cage and PCM and what not must get you up to ~1500kg and the Weissach pack saves 30kg on this weight since one of the big savings is the Ti cage vs the clubsport cage - do I have this correct ?

Sounds right according to the official spec
