997.2 rotors are bigger than 997.1 (380mm vs 350), but can't speak for the calipers.

997.1 GT pccb is 380, 997.1 GT steel is 350.
997.2 pccb and steel is 380

The 996 caliper is used up to 2008 for the 350mm rotor

Thanks! Forgot to clear that part up lol!

DO you know if the 997.1 GT3 RS has 350mm front rotors (steels)? Much appreciated

do you have Surface Transform carbons?

Hinz Motorsport

Yes, it does.

997.1 RS w/PCCB:

Don't mind the missing gold nut. I'm having my E88's bolts and center nut for the fake center locks coated the same color.


997.1 Non RS with w/out PCCB:

Sorta related, but can anyone who has actually done it confirm that 380mm brake rotors (only) from a 997.2 GT3 work on a 997.1 GT2 with its factory yellow caliper? The Porsche part numbers are officially different but I've been informed that it's a part number update more than a physical dimensional change. Thanks all!

997.1 GT3/RS/GT2 with iron use 350mm front and 350mm rear discs.
997.2 GT3/RS/GT2 with iron use 380mm front and 350mm rear discs.
All 997 GT2/GT3 Models with PCCB use the same 380mm front and 350mm rear discs.

The offsets are identical. Thus, yes, if your GT2 has factory PCCB calipers you can run the front 380mm pccb or iron rotors from the .2 GT3.

As an aside, if you want to keep carbon discs on the car, I have a set of 380mm front and 362mm rear ST rotors on the shelf for the 997 GT2/3. They also offer a 392mm front, but I have those on backorder at the moment.
