    Front brake rotors

    What do you guys think...Do I have to change my front brake rotors?



    The car only have 4800Km and 5 track days on...

    TIA

    I had the same problems. I took it to the dealer, and Porsche's stance is, if the cracks are longer than 5mm change the rotor. Porsche eventually changed them free of charge.

    I kept the old rotors and the cracks are only on the surface, the rotor is structually sound. If I was you I would carry on using them.

    Aparently this also happens on the GT3 cup cars, and the race teams wait until the cracks go from hole to hole, or to the edge of the rotor.

    My GT3RS is due in Feb, and I'm going to experiment with different pads for track use, I beleive what is happening is, the pad is overheating and then the rotors get to hot and crack. Hopefully by going to a more track orientaited pad, there will be less heat build up. Anyone else got any ideas?

    Regards

    I had the same cracks on my E55 AMG after 11000 km street driving. Of course they have been exchanged, even at no cost because I also made a complaint about "rubbing".

    To get back to your question: yes, they should be exchanged. But don't expect Porsche to pay for them.

    Max,

    I wouldn't take this rotor to a hard track-day, but it sure can handle some more street-driving. Keep an eye on them, and (as Sean mentioned) change them when the cracks are getting near the edge of the rotor.

    Hi,

    I don't change them as long as there are no cracks from the
    holes to the outside of the rotor. Still with cracks from hole
    to hole I'm fine.

    Cheers
    Thomas
