I now have 997tt rotors all the way around but am using 996tt calipers. I'm wanting to upgrade to the 997tt calipers. These rears would be a start. I just am not sure how to tell if they're 997tt rears or not. The seller doesn't know.

 

The answer is yes... but I would cross check that these are the bigger 350mm rears as it looks like the car is 997 C2 or C4... the 997TT has the 350mm rears.

BTW... it's a bit bizarre that the seller does not know!!!... would not be me dealing with them... you could get the part numbers of the caliper and check.

 

have you upgraded your fronts? you would be better off putting some Pagids with steel braided lines. the rear calipers are still 4piston. If the rotor size is bigger like Steve is saying, then you will need to get rotors as well.

 

you should read this entire thread before you change to 997tt calipers:
