Does anyone know if the pccbs off a a 997tt2 will fit on a 991s?

 

I dont know but if you check if the Brembo aftermarket kits fit both then you might have a chance. If not then there must be differences.

I can check rotor part numbers for you later if you want. Chance those might be same.

 

You might be in luck.
The 991 I450 [PCCB] lists 997 rotor part numbers.
Calipers are 991 #s though.

The rotors are the expensive part, so at least you are good with those.
The 997 calipers might bolt up, but you have to test that.

If you want real prices punch those part numbers in here:
