Ceramic Disc (PCCB) replacement

Took my car in for the air-con recall and as part of the routine safety inspection I was told my discs are coming to the end of their life (at less and 50,000 miles). Replacement will cost around £20k and reverting to Porsche steel discs will cost "much the same". I am thinking that an after-market steel replacement sounds a more sensible option - something like Brembos - probably from the US where there are a lot more Panameras. Any thoughs, suggestions, recommendations would be much appreciated. Thanks.

How did you get on?
My PCCBs have done 89k and are still almost brand new. No measurable wear at all across the surface of the disc. No lip or change of depth from the part Near the hub with no pad contact to the part that the pad actually rubs on.
They are supposed to last for the lifetime of the car. Which, being German, is north of 200k miles.
What pads have you been using?


 
I was going to post an update when I had a bit more info. However, since you ask, the latest position is:

Disk life is highly dependant on usage. Many reports of 100K miles plus for normal road usage, but just as many reports of very low mileage for heavy (read "track") usage and quite a few reports of poor life with claimed gentle use. Of course my definition of "gentle" and yours may be quite different. (reports based mainly on 911's). I have had a chat with a local Porsche specialist and his view is that the Porsche Centre may be "erring on the side of caution" He has measured all the disks and thinks they have plenty of life in them yet - time will tell.

Options:

1. I haven't yet found any aftermarket ceramic disks - still looking.
2. JZM will refurbish disks for less than £10K. Downside is that they need them for 30 days which doesn't work for me as the car is my daily drive. They do offer an exchange service if they have them in stock. Probably works for the more common 911 variants but probably not for a 970.
3. Steel replacements are readily available from the US from around £5k. Makes such as Brembo claim significant improvement over Porsche standard steel brakes.
4. I may have found a UK source for steel replacements for nearer £2.5k but need some further details.

I'll post a further update in due course, but unless I find a more economic ceramic option I will switch back to steel disks.

Hope this is of interest.

Very interesting and not really very surprising from the PC!

Would you mind updating us if you do find an alternative.
Thanks
 
Good evening gents, I have recently purchased an early turbo, was very worried about the immense cost should the ceramics need done. I spent some time on piston heads where the following came very highly regarded. Way more cost effective at less than £2k, again the main downside being the discs have to be sent away , I’ll see if I can find the thread .
