I had planned to pull my Dunlop Race Maxx 2's off my GT4 and go with the PS4S for all the reasons discussed, until I actually put some miles on the car. Now I'm not so sure. What surprises me about the Cup 2 comments are the noise complaints. I find the Dunlops super quiet, so much so that I wondered if that was typical for a track tire with less siping. They are crazy quiet compared to PZeros or the prior Michelin Super Sports I ran on other cars.
The second is just the turn in and crazy grip, even at pretty low temps. I pulled out of my driveway at 46 degrees a few days ago for a spirited drive, car was outside overnight, tires at 30lbs cold, dry pavement. Hit the hills and the grip was still fantastic and pressures came up to 33-35lbs. I expect that they will suck in the rain or seriously cold weather, but I've been surprised at how well they perform even down to the high 40's, which is about as bad as it gets here in my part of California.

Got 4's because they are way better in cooler temps and wet conditions than Cup's.

I've run PS4S on track, in the Smokies and on the street in my GT4. In my GT3 I've run both on the street and in the Smokies with the 4S and Cup 2s. You can't beat the 4S in the rain. They are a little slower on the track but very predictable. Driving in the Smokies with the 4S I didn't have anyone hanging on my bumper trying to get around me in the dry or wet. And you can get a lot more miles out of the 4S. If I were doing 6 to 8 track events a year again I'd put Cup 2s on the car with a second set of wheels and run the 4S on the street.

With the 4S at Mid-Ohio the rear feels a bit loose on turn in at T2 if using the kink before the keyhole. Other than that just a bit less grip in general. YRMV If you are hunting ultimate lap times it would not be your tire of choice.

No, I'm not at all. Just really liking the grip and sharp turn in of the Race Maxx 2 on the street and not sure I want to sacrifice anything. I've been very surprised. Did not expect to like them this much as a street tire. Fully expected to replace with the 4S, even considered doing it before taking delivery of the car, but then figured it would be worth trying out the Dunlops first. It will be interesting to see how far the Dunlops go and how they handle their first real rain test. That will factor into my decision come replacement time.

I haven't been out in the rain/wet yet and don't plan to.

FWIW I’m in the NE, and it gets cold and wet here a lot. I just did an autocross class (I’m not interested in tracking my car, but 30 - 50 in a parking lot is fun), and one thing that was emphasized was that at colder temps (below 40) high performance compound tires can crack. I’ve found also that getting caught out in the rain on PSC2’s is no bueno. VERY easy to slide out the back in standing water. I’m seriously thinking of putting on PS4’s as 99% of my driving is on road, and don’t want to worry about wet/cold conditions.
Separately, I’ve done a ton of snow driving in everything from SUV’s to 911 Turbo’s (4WD) to crappy front wheel drive Hyundai’s (got caught driving from Vail to Denver in a blizzard through the pass - scary as it gets). To me, the idea of driving a GT3 in the snow is nuts (clearance, grip, tread, $$$$$$$$$$$). Now the Turbo S - that’s a FUN snow car with the right tires.

I'm running the Cup2s as a daily and have 21k miles on the car now. I live in Norcal and it can rain fairly heavily in the wintertime. Used it then too... was it a handful? Yes. Was it dangerous? No - you just gotta drive slower than others. The percentage of time it rains is low enough that the tradeoff of great handling when warm vs sloppier wet characteristics is worth it to me. Now, I drive fairly aggressively even to work (who can't in this car?) with plenty of cloverleafs and twisty bits on the way - so I can get it closer to operating temp. I would keep that in mind as well.
