i drove a new fully loaded 991 c2s on Nurburgring for 40 laps ... chasing GT3s and doing low 8m bridge to gantry in someone elses car (on hard stock tires - porsche de doesnt let you drop pressures)
... so not coasting but car felt soft and floaty and the power was there but not immediate or visceral somehow
I hope that'll be the real edge for the 4

Not so much. Different linkage:

i drove both a '15 GTS and a C2S with the 7MT and couldn't tell any difference. They both have a slightly quirky engagement due to the spacing of 3 and 5 that requires a very deliberate shift. I imagine the 6MT in the GT4 is much easier to rip through, though I still like the 7MT.

Except Porsche hasn't confirmed that and others have said it's only a rumor. Part numbers are evidently identical in both cars and haven't changed at all in the GTS. This was just discussed over on the 991 sub forum about a month ago.

I'm assuming the collective conclusion is based on cracking gearboxes open to examine parts not on PET?

But what was the set up of the car, was it a PDCC/SPASM car or just a loaded up luxury build? As regards power, the 991S has slightly more power across the entire range than the GT4, so I can't imagine it would feel like the GT4 motor's got anything more. Should feel similar, though it will sound louder in the cabin obviously, which will provide a more visceral feel to things. The sound alone would be worth the price of admission for me.
But as I posted a number of months ago on my dev thread, the lightweight 964 still moves me more than the 6-3 on the road .. I feel the GT3 is too much for the road and just feels constrained there, and as Porsche South Africa suspends your motor and maintenance plan if you track - they have spies everywhere (and own the biggest track btw) - I don't plan to track the 4 ... so if it feels just about enough or only slightly too much for the road, I'm likely very happy!

Not directly relevant to the 991.1S but the ring laptime for the 991.2S is very impressive considering that it was again done with street tires:
Turbo + RWS + revised suspension F/R + revised PDK gear ratios/programming + wider tires + bigger brake rotors

Actually turbos are just a stop gap - hybrids will be the norm in 10 years, and full electric not long after that. I can't get excited by electric cars.

I agree. I also noticed the problems you called out, but those can be attributed to lesser skill, whereas shifting as early as the GT4 driver did almost had to be a conscious decision. I know people can get eager on shifts when they're excited, and the GT4 is undoubtedly an exciting car, but THAT early?
Still, as you say, impressive that the GT4 did as well as it did under those conditions.

Weight difference is 120lbs, and a C2S fitted with PCCB, PDCC and SPASM isn't gonna have much of a disadvantage to the GT4 in either the braking or suspension department. And the C2S has more power (total and per lb), better rear grip and a better drag coefficient. On most tracks I do think the GT4 will be faster, but the margin won't be very big. The 991 C2S, properly equipped, is still a very capable car on the track. Throw on SC2s and it's even more so.
