Thanks guys for all of your imput but here's a new question. Will the stock 996-997GT3 rotors work on PCCB calipers, my car had PCCB and was converted over to steel discs, not sure if there was a difference in the calipers or just painted yellow and not red. Want to make sure Im buying the right rotors

 

I hear the cup rotors are hard to find, any idea where I can get them.

 

Fantasic.............thank you so much
