I put them on my 15 GTS several months ago, 245's front, 305's rear. No problems with them. It was my first set of new tires on it, and I do not track the car. However, I've had Bridgestone's on other cars including earlier gen. 911's with nothing but good results. Got them through an independent tire shop.

Thanks for being the guinea pig!
How do they compare to the N spec Pzeros your car came with in terms of the ride quality, handling and grip?

I really do not notice a big difference one way or the other, but i don't push the car to extremes. They definitely were an improvement after having 6 year old tires on the car as they had aged. Car had 13k miles on it when i replaced them back earlier this year, aka 2021.
Due to rain later in the week I’ve only been able to put ~50 miles on them. Other tires I’ve run are the Bridgestone S02 and S03. I preferred the S02’s over the S03. PS4’s, PS Cup’s and Hankook V12’s. And Hoosier R6 at track.
So far, the New Potenza Sports are outstanding. Low road noise, fantastic dry traction, turn in and braking. No wet experience yet, and hopefully never as I don’t typically drive this car in the rain. I’m going to play around with tire pressure, so if anyone has any recommendations for 997 C2 I’d love to hear.
Just installed a set on my 13 C2. Driven one hundred miles or so and compared to the Pzeros they are superior in the dry. As reported by others the turn in is far better as is the grip. Road noise seems about the same but I do feel road imperfections more . Don't plan on driving in the wet so Ill have to let others review that part .
My only issue with these Bridgestone tires is that the Tread Width is 0.5" narrower than the OEM Michelin Pilot Sports on the 305/30-20 tire size (2019 Targa 4GTS).

This makes them look very undersized for the rim.

^ I've been comparing the tread width of the N-spec PS4S ever since switching from P-Zero tires to Pilot Sport 4S, which noticeably fill out the fenders more than the Pirellis did at the rear.
Looking at the measurements on Tire Rack, it appears the Porsche N-spec PS4S (on left) is wider than the "regular" PS4S (center) as well as the OE spec for another make (at right). It's 0.4-inch wider in one case, 0.7-inch in another. That's a fair few mm…
Not surprised that the N-spec tires provide more tread as the 911 has a lot more weight over the rear tires and will have different demands of the rear tires versus a car with 50:50 or 60:40 F:R distribution.
I would like to see a comparison on the same 911 a test between N-spec versus a 'standard' tire for acceleration / braking and track times. I would expect that the N-spec rear tire would wear better and last longer than a non-N spec tire.
Would be great to see the Bridgestone Potenza Sport come out in an N-spec.
