PP1 vs GT rear brakes

[Curse The Sky]

I know the Ecoboost cars get a solid rear rotor with a narrower caliper, but is there any difference between the regular GT rear brakes and the PP1 rears? I'm upgrading my fronts to the Brembo 6 pistons, wondering if I have to do anything to the rear as well.

same as far as I know. Only upgrade beyond that is gt350 4 piston or aftermarket
