You will notice less the difference in torsional rigidity than the additional weight of the Cab (about 150 pound weight penalty).

Very little difference in rigidity, particularly in normal road driving. The difference in a weight is pretty much equivalent to one medium-sized passenger, so easy to simulate.

Just got into a '17 TT Cab after owning a '14 TTS Coupe. I haven't noticed any real differences in torsional rigidity. The car has so much power the extra weight doesn't bother me (note that I also stepped down from a 991.1 TTS to a 991.2 TT).
The real question for me was "do I want the open air driving feeling?" After having a 996 C4 Cab a while back, I really wanted a convertible again.
Think about what you want your driving experience to be like. The option of having the top down overwhelms the other differences.

However, I DID feel the imperfections in the road. I did notice a smoother ride (sportier) in the coupe. Even with all the electronics it stiff felt a tad flexible more to me.
the cab had 50 miles the coupe 12900 miles same tire pressures same roads same time of day
I attribute the slower cab had more to do with it not being broken in. But the other issues....

If you're not going to track it and you live in Florida, I think it's a no brainer to get the Cab. Nothing is more fun than cruising with the top down. You can always add a By Design stage 3 or 4 to get extra speed and more sound out of it...

For regular street driving you will be hard-pressed to feel any differences between the Cab and Coupe. If you are a hardcore track junkie, then the coupe makes a world of difference especially with suspension mods. To me personally, I like the coupe for its lighter weight and rigidity. Thats just my own personal preference. Another point is that the cabs are more expensive when new, but cheaper in the used market.

It doesn't help that Porsche changed their website search engine so that it groups prices by dealership distance rather than prices across the country now. When I was shopping for my CPO TTS last year, I remember the price differential being there as well but buried in the options and miles. The website was more useful in the format they had at that time. If you waited long enough, a really good deal would pop up that you could grab if you were ready to put money down right away. I ended up buying my cab from across the country to get the best deal when it popped, as I had seen three others pop and disappear within a day or two.

2017 TTS Coupe: 2.5
2017 TTS Cab: 2.6
Quarter Mile:
2017 TTS Coupe: 10.5
2017 TTS Cab: 10.6
From a standing start, you’d be giving up 1/10 of a second. If you can feel that difference and call it “a tad”, then you owe it to yourself to get the coupe.

Empirically speaking, that difference is under the just noticeable difference threshold of human perception. It is imperceptible.

If you want a cab, get a cab. It’s probably one of the most convenient and least compromised of its kind. The top operates at the touch of a button, as does the windblock. The top is really more of a folding hard top, so it has the look and function of a convertible but the security of a hard top. I don’t find the C pillar blind spot to be a problem, but some do. You’ll have to decide yourself if the added body flex will bother you.

I figured. Just agreeing based on some numbers I crunched when comparing Ferrari 458 variations vs. the 488. A difference of .2s in the 0-60 may be noticeable, but likely not. It would be very close. I’d have to look up the peer reviewed articles I used before and crunch the numbers.
