Thanks guys. Will check them carefully tonite when I changed the wheels and pads back over but have not noticed any cracking or spidering around the holes at this point, but i wasn't looking specifically for that either.

If you are running the factory drilled rotors, like Bill said, ditch those and get some two piece slotted rotors. Coleman will make them for you and they are reasonably priced. If they have done these already for another customer, they will probably ask you to send them one of yours. A friend got their rotors for his highly modded 964 Turbo race car and they have held up well.

A friend bought the Colmans to bolt to stock 993tt hats around the same time, his are also still going strong.

I'd offer you one but I already gave all my old ones away.
Girodisk uses a 322x32 Colman annulus

Thanks Bill, I will have to figure something out since I only have the set of brakes on the car right now.
So Girodisc uses Colman annuli, why get Girdisc then? Do they do something different after getting them from Colman?

floating aluminum hats are nice things to have on a track car

Bills pics are perfect examples of why drilled rotors are not as good on the track compared to slotted. Have a look at the rear rotor, the holes are filled with brake dusts rendering them useless. Any gas extraction and cooling is eliminated very quickly when using drilled rotors with race pads.

Yeah, I noticed the holes become completely clogged after two sessions. Easily cleaned out w compressed air if needed. The cracking however does not go away. :/
