i am currently running oem PCCBs on my 997.1RS....
to be honest, when its time for me to change rotors i am going to replace the PCCB rotors with iron rotors. they just arent worth it to replace. the cost of replacement for PCCB rotors is about 10k per axle.... that means 20k for a complete set of replacement rotors!!!
they do have amazing fade resistance and are lighter in terms of unsprung mass but they are susceptible to chipping if you accidentally hit the rotor when mounting/dismounting wheels or if a huge rock hits the rotor hard enough.
its just not worth it.
