I replaced the pccb rotors on my spyder with brembo type 3. For how much they cost, I was disappointed with how long they lasted. I'm going to guess that OEM rotors will last just as long and will be cheaper. I bedded the rotors per instructions when they were brand new, and they ended up lasting only 12 track days. In fact, oddly enough, the pfc08 pads (barely) outlasted the rotor. The rears still look new, though.
My stock rotors look slightly better than Sam's after 10 track days, so will probably look the same after 13. Tiny cracks appeared after 3-4 days, but they barely grow at all. Unless deterioration accelerates, seems like OEM rotors are good for 20-25 days.

No easy one-size-fits-all answer for brake rotor and pad life. I for one am pretty hard on brakes and chew though them pretty quickly. My pad of choice on the 7.2 RS and my Cup is the Endless. Expensive, but well worth it. For a rotor on the RS I used the PFC slotted.

WTF. I'd be furious seeing that after 12 days on a car as light as Spyder. My Alcons on a porky M3 looked better after 30 tracks days - cracks would not even catch a fingernail (except they were worn so thin that the ridges were gone - I live dangerously).

I don't know for sure, but I believe Endless is only a pad manufacturer. They are a Japanese company and don't seem to have made much headway in getting into the pro racing ranks. In fact, one of their application engineers I met has now defected to Brembo. He said he was disillusioned with their marketing strategy. He also tells me that Brembo is now putting out some fantastic new race pads, but I've yet to try them.

If my rotors looked like that I'd have a spare set and check them after every run. Takes all of 2 minutes. You might get a few more days out of them. Probably wouldn't be my choice to start a 90 minute enduro on them.
I've heard a few say the Endless pads are pretty good. I've never tried them. I have used Alcons and had great results with them. Took them all the way down to the bottom of the slots and they still had not severely cracked. Tried a set of Colemans and they turned to crap in 3 days.
Two people with the same setup can get quite different results depending on driving style.

Aw shucks, thanks Lar (the guy who blows by me like I'm standing still).
Endless ME20 are supposed to be one of the best pads out there. I love PFC11, but my friend says ME20 are even better. The problem with ME20 is that they are much more expensive. I think like 60% more...

I have 13 track days on my rotors, with 4 or 5 on OEM pads and the rest R29. Porsche specs says rotors myst be replaced if cracks exceed 5 mm in length (used to be 7mm). Mine are about 7-9 mm but don't look too bad. Can anyone who knows tell me if this looks bad enough to replace? Looking at Joe's, they look pristine
I just ordered new front rotors – original factory ones should be toast next week after 11 track days & around 7,500km in total (4,700 miles). I’ve been running mainly at tracks that are very hard on brakes though, so not disappointed in OEM longevity. Looks like Brembo are the only aftermarket option right now. My rears have a long way to go so I just ordered a pair of OEM fronts (bloody expensive!) and will go aftermarket slotted when all 4 give up next time around.
Damn, that’s not good. Anyone else have bad experience with Giro? I have a few friends who track their 2-piece slotted rotors with great results so I’ve been thinking that would be the move – cheaper than OEM or Brembo (and I thought great performance & wear). Word is they will have discs for our car in 4-6 weeks.

Hoping PFC steps up to the plate, but they haven't made anything for the 991 or 981 yet...

Ideally I would like to use APs J-hook rotors if they will be available for this car. Type 3 seems to be a better option over drilled stock rotors.
I've seen rotors lasting for a very long time and some won't last a few track days. It all depends on how you take care of them.

Ganesh designed those pads for Endless and now works at Brembo. New Brembo pads are great but I don't think they are any different from Endless. I used both Endless and Brembo and didn't see any difference in performance. So both work very well!

Endless are awesome pads. I use the MX72 street/track compound on my 993 and if bedded in properly they are silent. They perform and last very well. I have just ordered the same compound for the 991 GT3 and these will be ready mid November (the factory in Japan is running off their first 991 GT3 fitments pads as we speak). The Me22 & Me20 are the perfect compound for guys like Sam & Max whos cars see more track miles than street miles. They would be most similar to R29 but infact superior. Endless fluid is equivalent to SFR Castrol but cheaper and is factory fill for GT3 RSR/Cup in European series....you cant miss them they are blue - this is what they look like fitted to my 993...
