    Anyone experience this on a non tracked car, or is this a clear sign it is tracked? Also does that wear affect my pad life? Will the rotors eventually have to be replaced - if so can you guess how long?

    Most of us ,I believe ,have non tracked cars. My understanding is carbon rotors last a long time if u don’t need to repeatedly brake excessively (on the track). They burn off in high temp repeated heat cycles and started to wear like steel ones. If ur car is tracked I don’t think the rotors will last 21k miles. I am not sure about pad life but they are nowhere as expensive to replace as rotors. I am no brake expert tho, but on my 458 and F430, both under or around 10k miles, the rotors have virtually no wear

    Is there a picture or anything showing the wear in question?

    You can’t tell from observation, unless the rotors suffered damage. CCM rotor material vaporizes, so the way to tell wear is to weigh them.

    That's what I learnt too ... or extensive wear which really shows.

    There was a terrible thread about it by our Portugese member Nuno here ..... lets ask him -> AlfistaPortoghese

    Ferrari did a PPI and there was slight wear on the rotors. He said it was very minor but based on miles it shouldn’t be there. He couldn’t definitively say it was from track use, he said it could have been pretty spirited driving on the street, but it sill caught me off guard. It was a 3 owner car. First one was 1,000 miles, second one put around 6 and then Ferrari sold it to the third guy and he put the remaining miles / apparently a old man. So when I was about to buy I was sure it was a good car but then this and valve covers sweating a bit were the two issues, which shut down my dreams.

    You connect a diagnostic computer to the instrument cluster ECU and there will be many parameters stored there related to CCM brake life and replacement. The tech has to know which one is the correct one to download for the current wear percentage of the brake rotors.

    What is the wear percentage of the rotors on your car?

    True!

    And true.

    My car was tracked and had to replace brake pads and disc brakes at 21.000mi.

    In my case, wear wasn't the issue, despite heat (its dissipation) being a problem. Surface contamination of the rotors was my problem.

    In non-tracked cars, I suspect rotors will last a long longer (5-7 times perhaps), but nothing lasts forever. An estimate will always depend on driver profile, environment, usage. Minor wear on a non-tracked car at 21.000mi doesn't surprise me, although it would be better to know how "minor" is "minor". You should ask for the wear percentage from your Ferrari dealer, like Mr. Brian Brown recommended.

    Kind regards,

    Nuno.

    10% rotor wear - how much did you pay for disc replacement? Did you know before you bought it was tracked?
