Here is the first of a double post with some updates. I update the table at the beginning to add the Base Cayman, Cayman T, and the old 2.5T Cayman GTS. Some of the items were hard to look up since the old GTS is out production. Also, my 0-60 times leave something to be desired. Every time I go down that path I find different numbers. It does not help that sometimes things are quoted 0-62 mph (0-100 kph) and sometimes 0-60 mph and then add in all the PDK, manual, sports chrono.... Take the numbers with a grain of salt. Especially when I look at the Thrust curves I have a hard time believing that the new GTS 4.0 beats the old GTS 2.0T to 60mph but that is what Porsche claims. It will be interesting if someone does a side by side drag race on YouTube.
I do not have the 2021 prices for a GTS 4.0 (even though I have put a deposit down on one!) - sorry Dry Side. I did guess 85,000 as a base price in my table - time will tell how close I get.

Look at the difference between the base and the T: 15 kilos. That’s pretty much the difference between 18” and 20” wheels.

^3rd radiator plus extra fluid add weight also.

Well. That settles that!

Here is an interesting comparison lap...
Laptime:
Cayman 718 GT4 with Romain Monti PRO driver: 1MIN 54.952
Cayman 718 GTS MANTHEY RACING with me as driver: 1MIN 54.440
On top the GT4 below the GTS
the GT4 is 100% stock with the Michelin sport cup 2 tire
2nd to 3rd gear a bit hard to pass on this exemplary!
The GTS have the Manthey racing preparation:
KW comp 3ways
Pirelli trofeo R tire with BBS FI R wheels
Nordschleife setup (car is a bit higher vs GP track setup)
half Roll cage Girodisc brake disc with endless MA45B brake pads
stainless brake line
Stock engine

Really interesting comparison and I appreciate all the hard work that went into making all of these charts and graphs for us. If you are a torque addict and love to drive your sports car as a daily (like me) then it's easy to see where the T4 cars shine. I love my base 718 Cayman but am seriously considering looking for an S in the future with a couple of performance options just to make my daily commute that much sweeter.

As many of you know, last year Porsche was forced by EU rules to start listing the weights of their cars according to their base configuration, not the lightest possible configuration with various lightweight options as they had done for decades previous.
The 718 Cayman/S weight was likely created under the old system, not the new EU system. I suspect that if you personally weighed a 718 GT4 and 718 Cayman S with the same seat and brake options, that the GT4 would not be 200 lbs heavier than the Cayman S

I appreciate all the data and analysis of the OP, especially providing the gear ratios for which i want to use to do my own comparisons to my current daily driver.
but the plots...why isn't RPM the x axis? it makes it much less intuitive presented with speed as the x-axis...rpm is the input, speed is the output. speed is a function of rpm and gearing.
again, thank you for the effort and analysis, happy gearing.

I can't speak for the OP but in my own version of the comparison I used speed as the x-axis as well. If you plot against rpm you can't see the cumulative effect of one gear after another. So you end up with essentially the torque curve at 6 different multiples/gears. If your goal is to see which achieves a given speed in the shortest time then plotting against speed is useful. Try it both ways and see what you think.
