I'm looking for the brake conversion mount for a 964 that adapts the spindle to use 993TT calipers and rotors. I have the one to use 993TT calipers/965 rotors but looking to switch to 993TT rotors without machining the adapter I have. Thank you in advance!!

I have a set of factory 964 Turbo 3.6 front uprights which allow the use of the 993TT calipers/rotors with no adapters...let me know if interested.

Thanks for the offer! The long term plan is to fit within H-prepared which unfortunately does not allow changes to the uprights. The 993 RS would definitely be the way to make things easy, light and lower roll center. Thank you for the offer, though!

So you are looking for 964/993Turbo big reds or 928 GTS big blacks front and 993 N/A rears?

I only have a set of 993 TT rears but it sounds like they won't be allowed. You also loose your handbrake if you use the 993TT or 993RS rears.

Actually the 964Turbo uprights won't be different. They are cast iron just like the 964 but allow for the mounting of the caliper without adapters and will use the 964 turbo 3.6 front rotor.

thank you! actually that is the set up i'm trying to run: 993TT calipers in front and 993C2 in the rear. i used to run the front calipers a long time ago with the 964 turbo rotors so I already have the adapter for that. i'm looking to make the switch to 993TT 2-piece thicker rotors and it was my mistake that the offset was not the same for both rotors. looking to make the easy swap to a new adapter rather than play the guessing game machining mine down a couple mil at a time. thank you!

There are hats available for the 964 turbo offset but they are rare and hard to find. The only differences between the 964T3.6 rotor and the 993TT rotor is the 993 hat is 5mm shorter than the 964. Rotor is the same 322x32mm for both. I am using the 993TT steel hats currently for my track car with slotted rotors on my 964 with 993 uprights. I do plan to switch to an aluminum hat one day.

Good luck

nice set up! that is the reason why i'm searching so hard... there aren't too many rotor options for a 993tt let alone the 964T. i can keep the cost reasonable by getting a couple uses out of the 993TT hats and buy an aftermarket slotted rotor for them without having to go the route of expensive floating hat (girodisc, etc). with that being said, i wouldn't be opposed to a 964T offset on an OEM style hat that i can bolt the same aftermarket discs on an OEM hat. i'm sure that would be even more difficult to find than an adapter bracket for my calipers with the right offset for 993TT rotors!
