This website also has a list:

If that list is to believed that's some pretty solid gains for 992.

Read the Technology Workshop guide. The chassis has been seriously modified/upgraded.

Not necessarily. That chart really doesn't mean anything. Not only is it developed by the marketing department for public viewing, but even if it did mean such, cars can be cancelled late into development.
It is not the same. Very different.
Most are according to jumper5836:
911 A-F: 3,500 NM/deg (????? I seem to recall reading something like this somewhere)
911 G: 7,000 NM/deg (according to burgermeister on Pelican)
959: 12,900 NM/deg
964: 11,500 NM/deg
993: 13,900 NM/deg
996: 20,100 NM/deg
996.2: 25,100 NM/deg
996 TT: 27,000 NM/deg
997: 33,000 NM/deg
991: 40,000 NM/deg
Those are coupes. And to be taken at face value; none are proven or documented.
Fun comparison.....
Lamborghini Countach: 2,300 NM/deg !
It has been stated that base and S 992s receive the same width fenders.

The 992 chassis is not the same as 991.1/991.2.

Just saying the S is wider body since it's the one released. The base models will have he same wide body.

R&T claims the 992 is 5% stiffer than outgoing 991.2. (click for source)
R&T specifies the 991.2 rather than saying 991; are they are implying a 991.2 is stiffer than a comparable 991? I don't know.
Anyway, the 991 is supposedly 40,000 NM per degree.
5% increase would place the 992 at 42,000 NM/deg.
The same R&T article also says the engine mounts (says nothing about engine centerline) have moved forward a not-really-believable 6.6" (168mm), rather than the 20mm previously quoted.
While everything is relative, I would not say the 992 is just a "991.3." The chassis is entirely different and reengineered. Things changed include the wheelbase, suspension geometry, engine placement, track width, etc. Engineered from the ground up? No, but nothing ever is.
Anyway, the 992 chassis uses around 60% aluminum, 991 was around 30%. That statistic alone is evidence the chassis would have to be comprehensively reevaluated for stiffness, deflection, handling, crashworthiness, corrosion resistance, fatigue, etc.

The 991 was stated by Porsche to be 20% stiffer than the 997, and 5% less stiff than the 992. Easy to do the math. So stiff that after nearly 8 years, they "only" could squeeze 5% out of its replacement model. That puts it around 37-38K nm/deg.
