6 piston Calipers doesn't matter same part number...but you will be using 350mm Turbo rotors...due to rotor offset and the uprights on the car. If you do aftermarket rotors just make sure they are 350mm for 997 Turbo cars.

To do GT3 rotors in 380mm you will have to swap out uprights to GT3 uprights to get the rotor offset correct. Plus you will need to do rears to GT3 spec too to balance everything out.
