Rotor Question
I searched, but did not see anything.
I only know of cross drilled OEM rotors for 993. Our 993 is a track only car and cracked rotor is a normal occurance. Would 944TS or 928S rotors fit the front of 993?
Thanks

No, if you have 993tt fronts there are options but there are no other choices when using stock 993 or 993RS/tt rear

BTW, the rule 'o thumb is that the cracks should not extend beyond halfway to the next hole or to the edge. Short of this, you're fine and no need to worry.

FWIW I installed cooling ducts that made a world of difference in front rotor life. I won't say it doubled it but it was up there. You can get the expensive ones from Gert or the cheap ones at MA Shaw and your local Leows.

I suspected that OEM is only game in town. The car has cooling ducts, but given the location of the two oil coolers (stock location and another on the same location, but on the driver side), I do not see much room to get the hoses to the front, so they are not getting full clean air.
The car has two drivers, so rotors take a beating. I just ordered new ones and have to remember to carry the spare used one just in case. I hate using drilled rotors because I find the the cracks unpredictable.

When our 993 had two drivers I not only added the air ducts I added the big reds. The braking performance WILL NOT improve. But the longevity of the rotors was remarkable- one set lasted the whole season- we were doing three sets per previously. Even with an oil cooler the ducts should be working- did you get the plastic "channels" that Porsche has that direct the air over the brakes? Also Porsche makes a set that fit under the car but any offs or uneven surfaces and they're history.
I miss my 993.

What plastic channels for the 993 are you speaking of? Different than the plastic deflectors under the car?
I'm about to go big reds and try to run brake ducts around or through the oil cooler. How did you direct the air toward the center of the rotor?
Sorry to hijack, but Nader has the hot brake/cracked rotor problem so this might be helpful to him, as well.

Big reds will not do for now as the car races as a stock class car in PCA. The hoses are pushed next to the oil cooler, but are not connected to the air ducts in the bumper cover cause there is not enough room next to the oil coolers to route.
The part number for the air ducts are 993 341 083 00 and 993 341 084 00.

I'll have to see if I have these on the car and what kind of shape they are in. The backing plates are already removed.

There's a dIY for running the hose THROUGH the oil cooler area. I haven't done it yet. I think it's on P-car.com
Re the deflector part numbers, those are already on the car. I was wondering if George was describing some other "plastic channel".
