Trouble with rotors - where to buy OEM?

[steve_wilwerding]

I replaced my rotors about two months ago, and this weekend was the first time I was on the track with them After just two runs, I was experiencing terrible brake fade. I came home, threw my old rotors on, and the brakes were back to rock hard.

I ordered the rotors from a Porsche shop, and I assumed they were were genuine Porsche rotors, but looking at the receipt, it appears that they are not OEM rotors. Has anyone ever experienced this problem? I assume that as these rotors heat up, they're warping and causing the fade.

I guess my real question, since it appears that the rotors were the issue is, where is the cheapest place to get OEM rotors?

Just a thught, did you put the front right rotor on the right side and the left on left, non OEM rotors are sometimes not marked.. "Sunset Porsche/Audi" Oregon. for OEM rotors

Unless the steering wheel was shaking on hard braking, the rotors wouldn't be warped. brake fade will usually occur initially when using new brake pads/rotors at the track, especially after first or second session on them. just let them get to ambient temp and they are ok. Don't think that rotor is bad, no matter who manufacturers it.

Did you change the brake pads at the same time? If not, they'll be shaped after the old worn rotors and have a reduced contact area against the new discs. This will cause a soft pedal.

I used the old pads. I have had the rotors on for two months, and had done enough hard stops on the street to "bed in" the old pads with the new rotors. This weekend was the first time I had the car on the track with the new rotors, and they started fading after only a few laps.

I talked to a local Porsche mechanic today, and he says he sees this all the time with aftermarket rotors. So, I guess I'll get a set of OEM rotors, and will continue to do so in the future.
