"Installing 997TT front 350mm discs and 6-piston calipers is fine. The rears are not recommended due to the major piston size increase, just as on the 996TT. You can upgrade to 350mm rear discs with your original calipers using a proper spacer and longer bolts. I know that these are stocked by the Brembo distributor.
In regards to 997TT PCCB's the fronts would work provided that the factory adapter bracket and additional bolts are used that adapts from the factory upright 142mm spacing to the 225mm required with the PCCB calipers.
For the rear, you could not use the 997TT PCCB calipers because of the piston size increase. You would have to use the 997 non-turbo PCCB calipers. "

Hi m8
I am not changing calipers, I am keeping the PCCB calipers and pads, as they are much more powerful and ceramic pads are OK to use with steel rotors.
Its just the rotors I am changing from the current PCCB (350mm all round) to steel as I track the car a lot.
So are you confirming 997 Turbo rotors front and rear are the right offset and will fit OK?
