993 TT calipers/disks on a 964 C2 Rear

I have bought a set of 993 TT/C4/RS calipers front and rear for my 964 C2. Front seems not really to be a problem because I think I can use the rotors of a 964 3.6 T, together with a pair of the right adapters. But for the rear is a different one, there is no standard rotor of 322x28 mm which fits. Anybody knows a solution ?

alternately to retain the parking brakes and use the 322x32 rear you can, pin a correct center section into the 993 rotor, that's how it was done on my 911 w/ 993RS rears
it looks like this

I haven't seen a rear 993TT caliper fitted to a 964. I think it would be almost impossible to fabricate the correct adapters because the suspension arm is in the way. Usually people go with a regular 993 rear caliper (plug & play) and a 964 rotor or the 964 RS rotor if you want it to be cross-drilled.

Thanks 4 the pictures ! It seems to be a very difficult thing to put the 322x28 on the back. Ithink I have to consider to go to RS disks and 993 C2 calipers at the back and a C4 m/c. Thanks for all the information ! By the way, my region is Europe, The Netherlands.

I did the exact same rear setup as Geoffrey, also removing the parking brake. Same style rotors up front but slightly larger at 332mm, and also removed the proportioning valve. Running Pagid Yellows up front and Pagid Blacks in the rear. Works great. Much more settled under braking, better modulation, and plenty of braking power.
Jemm Gamroth of Rothsport did this work for me. I am very happy with it on my RSA.

Geoffrey gave up the parking brake and used a hat/annulus from, I believe, AP. I think that he documented it in one of his race car build threads.

I have a set of 993tt big reds and wanted to put the full set on my 964 C4.
The rear has been an issue as far as information gethering.
Is it possible? How can I achieve it with the park brake?
Also what caliper adapter do I use for the rear then?
Thanks
John
