Your specs look pretty good. Because you can't really dial more than -2 camber in the front, you can run them square, taking the max camber up front and matching it in the rear. Caster and toe look good.
It has little to do with how the front suspension works and more to do with the balance of the car. You can run these specs on any modern 911 and would work well.
I'm not saying they won't work well, I'm just saying the specs that Porsche came up with for the GT3 were dialed in for that car. And when you set alignment, that's a static setting. But under dynamic load (ie, going through a corner or hitting a bump), toe and camber changes as the suspension moves. It is reasonable to believe that Porsche went through a lot of engineering on the GT3 specifically (with this suspension geometry and this ride height and this wheel path and this width wheel and this tire and this weight distribution, etc etc) to arrive at these specs.
That doesn't mean we can't look at the basics of what more camber, different toe settings, etc do and make some educated guesses about what might be an improvement. And sometimes it is, but sometimes it gets worse and needs to be tweeked more through trial and error. That's why just adding wider wheels and tires isn't always better. Or lowering a car sometimes causes the car to drive worse. Sure you might lower the CoG but at the same time mess up the dynamic suspension geometry and introduce things like bump steer.
Without having any other data, why not start with GT3 specs and see how it works? But that may be just a starting point. Personally I would start with a trusted local shop that has been working on 992 setups for other customers, leveraging their experiences around what has worked well and what didn't. For now I'm sticking with Porsche factory spec.
I received an email from Porsche this morning that manufacturer is starting soon, along with my VIN. Number, I’m beyond excited though TYD still shows manufacturing is 9/1/23 I hope it’s sooner.
Went to Byers Porsche and took delivery of Kermit. I showed up late in the day so it was a quick process. Had taken car of paperwork earlier so i could enjoy the moment better. My daughter came with me so that was fun.
first impressions… the car doesn’t need anymore power for the street that is for sure. I drive a grand am car (997) on the track so know what power is. It feels like there is a lot more sound in the tank after 4k rpm so I am happy with how that will sound. The fit and finish is incredible. The position of the volume **** is perfect and it’s easy to operate the infotainment. Much better than my wife’s GLS. Harmon Kardon is amazing and super happy with that. Lizard green interior goes just fine with the python exterior. Glad i did the glass sunroof love the open air feel. Saving 50 lbs by doing carbon fiber roof and no back seat is a none issue with how much power this generates. The five people that drive it yesterday all noticed how nimble the car felt vs other 992’s that they have driven. You just point and shoot the car and it just goes! It’s flat out in the turns and very comfortable on the roads. Feels very similar to my wife’s 991.1 gts in the fun factor but the 992 is just a superior platform. Those hips in the rear view mirror are very much like my 993 but even larger. Home run Porsche I am super grateful to own the best Porsche offering for the street hands down.
04 The manufacturing process of your Porsche has now started
We are thrilled to inform you that the production of your Porsche has now started. The Porsche sports car models 718, 911 and the all-electric Taycan are produced in our main plant in Zuffenhausen. All 718 and 911 derivatives – from series production vehicles for the road right down to pure race cars – are being produced on the same production line, whereas the Taycan has its own highly advanced facilities in Zuffenhausen. The Panamera and Macan models are produced in our factory in Leipzig. Your Porsche will be assembled utilizing the just-in-sequence method to maximize flexibility, quality and overall efficiency on the production line. This tried and tested concept relies on minimal stock replenishment. Our sophisticated logistics and production systems ensure that your Porsche is built exactly according to your specifications. Due the fact that this will take a little time, we would like to offer you an insight into the development process in our research and design facilities in Weissach.The Porsche R&D Center has been located in Weissach since 1971. Around 6,500 employees work here. Design offices, test stands, workshops and our motorsport department are all close together. The result is a tightly linked and coordinated development process, from the first sketch to the finished vehicle.

Congrats! Looks awesome!
I know it would probably weigh too much, but I would love a 992 Targa T. Maybe they could save a lot of the weight by not using a mechanical roof mechanism. Carbon fiber manual roof? Though a lightweight glass Targa rear bubble would probably crack if you looked at it slightly wrong

A few points:
1. There's a reason anyone who spends enough time at the track won't track their GT3 or RS with factory specs and that's because they are setup for safety and not optimum performance. The same applies to virtually every car on the road.
2. Guessing, even if educated, shouldn't play a role in setting up any car. You cannot dial more than -2 degrees on a stock 992 Carrara. -2 degrees is, as another RLer described it, Camary setup for a 911. Therefore, Maxing out front camber and matching the rear is the default, tried-and-true way to set up a 911, any 911 not just 992s, with factory suspension. Caster can stay at or near OE spec and toe should be set at or near zero if one desires quicker turn-in. These are not specs for a track car with a proper suspension. This is just how a stock 911 can be setup if one desires better performance than the safety-compromised alignment specs the car comes with.
3. There is ample data. There are may raceshops that do this day in and day out. Some of us unfortunately don't have access to them, like me. But I don't need to. I have experience and knowledge from setting up other 911s that I can take to the dealer and have them set up my car the way I want it. There's nothing wrong with the factory specs and that will be just fine for most people.
I find the car out of the box to be fantastic. It's the reason why, though I'm prone to mod, I don't believe I will tune my car or do exhaust. I also contemplated getting stickier rubber on wider rims (to accommodate N rated tires). The car is so wide that extreme summer tires do an excellent job of keeping the car glued to the road. I found it very hard to get the car to break traction. However, when it comes to suspension, my personal preference is to definitely dial that in a bit more. I believe it will take the car from fantastic to exceptional.

finally @duktail ....been busy but let's meetup soon for a candy color session after esoteric!
Hi all! It’s been a while but I’m glad to see this club still firing. Wanted to pose a few questions for the group:
-Brakes: has anyone upgraded to S/GTS/AP Racing? I really wish I could have specced CCBs so trying to scratch that itch
-Exhaust: any aftermarket exhausts installed yet? I know there was a JCR group buy, but trying to get some real world recommendations before I purchase
-GT4 RS upgrade: I have the opportunity to swap into a 4RS at a reasonable price, but as my only car I have hesitations living in a big city. Owning both isn’t how I’d like to allocate capital right now, so it would have to be one or the other - what would you do assuming no commute but garaging in a big urban environment with bad roads?
