I have done numerous trackdays and Porsche event days and yes there is fade but after much more prolonged abuse than with an M3, I have only really suffered fade with a 911 after 45 mins of really hard braking with the pedal going softer after about 30mins but even with the softer pedal it still maintained the same braking performance.
I don't think any stock disc/pad setup will never fade after prolonged abuse but my point was that Porsche brakes are much better prepared to cope with track work than what BMW offer on the M3. |

...and the fade that you (footie) experienced was fluid fade.
Loss of pedal firmness = Fluid fade. Loss of friction = Pad fade. Loss of both = A fully heat soaked system. When the pedal becomes soft, but still maintains good braking performance (still providing sufficient friction), that is due to your fluid boiling. A fresh fluid, and one with a higher dry boiling point, could have most certainly cured that. Also, if your pads were wearing down, that also adds to the temperatures transferred directly to the caliper and fluid. Many people forget that brake pads also act as a heat sink...another great benefit of the Brembo BBK's...larger pad shapes, both by swept area and volume. |

P.S. I did get to try two otherwise identical 997s, one with ceramics and the other normal steel discs, the braking performance is remarkably similar but as expected the ceramics never appear to go off, well not during my time with the car. Though I still wouldn't go for ceramics, it's an excess of money that I feel would be better spent else where. |

That didnt go over so well when people were burning through pads every 5000kms, so they did away with the Brembos in a couple years. I believe there was even a class action lawsuit filed in California over this! How often are you guys really slamming the brakes at 130mph down to 40mph over and over again on your daily drive to work!??! and if so, I want to know your route to work, because I'll be driving that one too with my new BBK, heck i might even get one of these! |

I noticed fade driving a canyon road in Malibu and not even driving hard. Probably due to the OEM setup more than anything, I'm sure race pads, fluids and ss lines would have made a difference.
My car went hard at the track on my Stoptechs at Spring Mountain. Not one bit of fade and damn did they grab hard each and every time we had to slow down. It's nice not to have to worry one bit about your brakes holding up during track use. It's worth it to me, I didn't even choose a color that was pretty.
