At what point do you replace your rotors?

I think I have checked with frozen rotors and they did not have them for the 993 C2. Ill check again thanks. Even if I can't find a good alternative they really do last pretty well for what they cost.

I couldn't find slotted 993TT rotors at FrozenRotors.
Cryo-Rem does your rotor for about $30 each I want to say.

I've used FrozenRotors for years. I can't say how much longer they last other than yes they do last longer.
I have since switched to slotted rotors (still cryo) and have not replaced a set yet. I believe they are manufactured by Coleman. These last infinitely longer than Porsche.
The problem is the Porsche rotors are made out of some alloy of cheese. It takes nothing for them to crack. I was cracking them with hardly any wear. On the other hand they are cheap considering they are from Porsche. Switching to a better quality rotor makes all the difference.
I know these are available from frozentors.com and also from KVR Performance in Canada.

Geoffrey, were those notes in the A-K stock classes or the 'stock' GT classes? I know they can pay close attention to the factory race cars when they dictate what wheels you can use in some classes.
I have never seen this in the 'stock stock' classes, has anyone else?

I have seen it in A-K stock classes primarily with the 996s and GT3s. The GTC classes are allowed to use any iron based non floating rotor of the same thickness and diameter of stock.

Ouch, I guess I need to do some more research before making the switch then. Thanks for the heads up.
I guess the difference is that on my SC they were one piece, not the floaters they make for the 996's

Dave,
Here's something I just found while brousing the Brembo Racing Brake catalog. Might be of some help to all with drilled rotors.
BRAKE DISC
Check carefully the disc braking surfaces.
The disc can't be used again if:
- on the braking surfaces there are cracks having length higher than 5 mm; in case the crack
begins from the external or internal diameter, even if the length is shorter, the disc must be
replaced (see Fig. 8).
- It has a wear of 1 mm compared to the new thickness (0,5 mm on both sides);
- The braking surfaces show scorings, which can damage the correct pad/disc contact.
