Page 14 of their parts list has race only parts for the GT3:

Front is almost identical to 997. Wow rear is different. How is camber adjusted in rear ? On 997 we had puck and trailing link.
Wonder if that cup solid link could replace the 4ws control thing.... For those that might want to try it. Curious on that rear upright too to allow for 18" wheels....
I'm sure Someone will experiment soon

Fascinating read. Thank you. Nice to see the gt3 suspension w/o wheels. It will be a while until I get the equip to do the center locks, remove the wheels and check things out myself.

Street cars are brembo. Cup cars are pfc. Wonder if mounting and spacing is same on street parts?

It appears that the uprights are the same with some modifications done to the Cup car (some mounting brackets are machined down) but I'm assuming the mounting points are the same. I would be interesting to see if Cup car PFC brakes could be directly bolted onto the GT3.
The rear camber is adjusted via eccentric adjuster bolt and the arms are length adjustable.
The Cup cars rear lower control arms are mounted higher and the lower brackets on the upright are machined down. This allows for 18" wheel fitment.
Also, I think there would be no problem replacing the rws actuator with a toe arm from regular carrera or possibly the cup car.

That's the few thousand dollar question regarding the breaks. Would be awesome to install the Cup Car's PFC breaks.
Did you see a disconnect port (plug) for the cable on the actuator itself? If you want to switch it out with a cup car toe link.

Not sure you really want to do that. I doubt the performance is that different (with same piston count and rotor dimensions). I think one desirable trait one might like to borrow from the Cup's brakes & suspension is the ability to run 18" wheels, but that looks to be impossible from Bart's post (seems the Rear Wheel Steering and its geometry prevents that).
If I were to consider upgrading the brakes, it would likely be Movit carbon or similar.
