Would anybody know if OEM 3.6TT rear rotors will fit on a 993TT ?

No they won't completely different.The 964's use a 299 x 28mm rotor the 993TT uses a 322 x 28mm rotor. The hat size is different as well and won't accommodate the handbrake.

Hey Anthony,
Do you need a spare set of OEM rears for the 3.6 ?

Sorry Elliot. At the rate I am driving mine i won't need another set for decades. No doubt they are of value to any of the 964 turbo owners.

Cobalt - Do you have a 3.6TT ?? I didn't know you owned a 993,... or is your track car a 3.6 TT?

I have an extra full set of 3.6 T rotors as well. They are different than my 3.3T rotors, so I went back to the original sizing for my car.

You know what Elliot means Is there a difference? The 3.6, 3.3 TL and AR all use the 299 X 28mm rotor with the 34/40 mm piston caliper in the rear. Are the hole patterns different like the fronts?

For reference,... this was our conversation back in Oct 2015...

I still have all 4 rotors, and the fronts were from a 964 3.6 ... Post #12 I listed the part numbers, and Post #13 Anthony responded with the facts...

Steve,

That was regarding the fronts. Elliot is talking about the rears. The fronts are definitely different. The easiest way to tell the difference is by counting the holes. The 3.3 has a 4 hole 3 hole pattern the 3.6 has a 5 hole 4 hole pattern. I believe all the rears are the same and have a 4 hole 3 hole 3hole pattern.

Ahhh, cool. Thanks!!

Never committed that to memory. You're like a BANK vault Tony!

Yep, now I see it in those pics I posted here too.... both fronts & rears for my 3.3 are 4/3hole...

Thanks for the clarification. This is good news for me,.. since my extra pair of rear rotors could sell to a 3.3 or 3.6 owner,... and the fronts only to a 3.6.

Thanks for asking the question Elliot. I learn something new every day,... and then forget half of it the next day....
