Oh wow - my memory isn't good enough to remember in which of the many articles I saw that. But I was particularly interested (and happy) to see it, because it was my fear that with the 5% larger diameter rear tires that the Manual's gearing would effectively become 5% taller. I figured Porsche might be happy to save some Euros and show a bigger advantage for the PDK version this time and just skip re-gearing to offset the larger tires. But they didn't

I've also seen this, not sure where any more.

"Both transmissions are carried over from the 991-series GT3, though the PDK gets slightly bigger bearings and a better oiling system, plus a different control module to enable it to work with the 992's new electronic architecture. The manual transmission's ratios are unchanged, but the final drive ratio has been lowered to account for the 992's 21-inch rear wheels."

PDK transmission and clutches (2) are life time. LN Engineering issued advisory regarding transmission fluid change;
Racing: after every weekend
Fast driving and DE: twice as often as recommended in owners manual
Coffee and cars, dinners, etc: per owners manual.

if you follow this than transmission should last 100,000+ miles.

The Manual only requires changing the oil every 93,000 miles (no greater frequency recommended in the race track supplement).

I have been saying that my SWAG is that the wing is somehow removable sort of like the 991RS.. the more I look at it the more I'm convinced.

However, as we have seen touring models driving around without the ducktail even, from a marketing perspective I can't see why they would Allow this.

A removable swan neck wing would be awesome! "A lady in the streets, and a freak in the sheets!".

And the legal liability of driving with max front downforce and minimal rear downforce...

OP, have you ever investigated laundry appliances? Are my missing socks huddled together on a grassy knoll somewhere?

NBoost, seriously?! You know PTS isn't offered on laundry appliances and they only run in circles. What fun is that? Nor N Boosted appliances that only go in one direction. There were socks left behind on a grassy knoll somewhere. Being they only cost $2/pair, I wouldn't sweat it.

As stated in quotes, they are not using the carrera S gearbox for the manual. The GT3 always stays in it's own lane. The fast lane. Not the eco lane (7th ratio)

The rear wing is not a DIY touring.

I think we all agree on this but is it the MT a carryover from 991.2 or a new 6 speed which shares components with the PDK?

if it shares components with the Pdk, then it would need similar shifting technology currently in the Carrera S since pdk gear configuration is different.
Thinking about your answer, I conclude it is a carryover

It is a carryover as stated here: https://www.motortrend.com/cars/pors...review-photos/

And the old 6spd already shares components with the PDK (same outer case, for example). This is why it's only 37 pounds lighter than PDK (while the Manual GT4 is considerably lighter than its PDK counterpart).
