I have tested a 348 with a set of ceramic TAROX disc from Italy. www.Tarox.com
I thinking of getting a set for my 348 instead of the grooved discs. They work really well even fronm cold and no noise.... |

I Just love hearing that you guys USE the car as intended.

Yeah - my rotors show small cracks around the cross-drilled holes. I imagine since the rotors on the challenge car are slotted, they are less susceptible to heat cycle relate damage such as this. On my car it wasn't a case of pads being too low, just that the Rotors haven't handled the hard use and heat very well. I'm in the process of finding out whether Ferrari will contribute to the replacement cost :-) |

"I was pretty unimpressed with the life of my 360 rotors."
The rotors on my F355B have the opposite story. I bought the car with 22 K miles on the clock in june of 01. I don't know the state of the rotors at purchase time (new or turned), nor the state of the pads.
After 5 track days on standard Ferrari pads, I was getting to the point where pad fade was continuous (and an off track excrusion). I did some research and found Ferrodo DS2500 pads and had them installed Nov 02 along with ATE SuperBlue fluid.
These pads rock! While I can get close to fading them, backing off a triffling and they come right back. Good bite, takes a bunch of heat, and with my usage pattern no squeel. They are streetable down here in texas, but might not be ideal farther north in the winter.
Anyway, back to the story; I am getting 7-8 track days on a set of pads (ignoring street miles). And one track day I went through a set of rear pads and scored the rear rotors. The mechanic had them measured and turned, and they were just barely over the acceptable limit.
Now on my 3rd set of DS2500s and up to 30 track days and 18,000 total miles since obtaining said car. Will probably have to change rotors this winter. I consider this very acceptable rotor life; given the operating circumstances. Whether this is attributable to A) driver (not likely), B) Brembo Rotors, C) pads, D) luck; has not been determined. |

i don't know if this helps or is even something that you know about already. the local Viper Club vice president owns a compnay called Great Brakes www.greatbrakes.com and they rep the EBC brand in the US. They may be able to answer a qestion or two and are pretty good guys to deal with.
I am not associated or involved mearly passing on a source of info |

Hmmm, this is one BIG concern for me. I was pretty unimpressed with the life of my 360 rotors. I'm just about to replace them at 12K, with on 4 track days to go with the road miles...
I'll be asking Ferrari this question though before I confirm my order - this might tip me back to keeping my current car and buying a challenge car for 100-120K. |

At 4,000 miles, so far, so good; will be putting on the track in late Oct. and will let you know. |

james: i'm sure there a sanctioning body restriction, but ultimatly, if it were worth the time, i'm sure porsche would petition. all porsche now has THREE diff. pad cmpds. available for pccb system; it would seem that the pccb is not a "universally" better alternative to a conventional system. also, the various pad cmpds. are made for differing heat ranges, as the pccb rotors "overheat" and literally turn to dust under extreme use. some gt2 owners that have used the car on track, and complained to porsche NA, apparently hit a brick wall, and simply "upgraded" to the steel system.

also, the carbon/ceramic brakes as seen on the gt2/gt3 and 360cs are radically different than the pure carbon brakes on lmp, f1, etc. race cars.

That is interesting about the GT3RSR. Is that because of a rule req.? |

seems like the gt2/gt3 pccb commentary boils down to either 1. freak failure? (people recounting only gentle street use, and that leading up to failure of the disk), or 2. "improper" pad choice when the car's put on the track; as in, the street pads over heat on the track, and eat away at the rotor, which leads to the destruction of the rotor. with respect to the 360CS, i suppose it would be up to your wherewithal, and intended use of the car, and if different pad compounds are reccomended for different applications.
if it were me, i don't think the 2-3lbs. / corner would be worth the added expense/concern, especially if that unsprung weight could be made up in wheel choice.
interesting anecdote: the new GT3RSR race cars still feature the conventional rotors.

I have seen on the Porsche site Rennlist discussion of the GT2 ceramic brakes, with some unfavorable comment.
As I am waiting for a Stradale, the subject is of interest. Any experience/opinions? Should I anticipate staggering pad/rotor replacement costs? Thanks, Will |
