Help to ID & source rotor w/ Big Red Calipers
 

Hi folks,
I need help identifying these rotors. They are on an '83 SC converted to a turbo (engine, flares, etc). I think these are still SC struts and spindle, with Big Red calipers added. I need to replace the rotors (cracks starting to propagate from the cross drilled cooling holes). Do the rotors come separate from the hats?

They are about 12 1/2" dia (may be 313 mm seems close) and 30mm thick now (so 32mm new maybe?)

Thanks for any assistance!

I have an 07 Cayman S, and the calipers look similar.

Have you noticed - the picutre shows - the wear on the rotors? you're not getting a full pads/rotor contact there, you're missing about 30~40% of the breaking power with those calipers. Might look cool but... M2c

yeah, on the contact surface, I just stuck a set of new pads in. I need to resurface the rotor, obviously not making full contact.
I measure the diameter a bit closer and I think they are 322mm rotors.

I have searched and find lots of upgrade kits, but no replacement rotors.

How many bolts securing the rotors to the center hats? Closeup of the hardware?
May be stock 993T rotors installed on aftermarket center hats, could be aftermarket Coleman rotors.

10 bolts securing the rotor to the hat. Forgive my ignorance, are all 993TT rotors two piece (rotor & hat type)?

993T front rotors are 2-piece, and by the 10-bolt count and the D-shape of the nuts, that's what they are.

Thanks Chris! That should make sourcing much easier.

Perhaps helps that Pictures
Since are 322mm in Front and 304mm Rear
Picture shows the number for the the 322mm right and left side
