Ceramic brakes?

[keep it lit]

997.1 gt3/rs 350mm (pccb & steel) front & rear discs
997.2 gt3/rs 380mm front (pccb & steel) with 350mm rear (both pccb & steel)

right?

No. All 997 GTx cars have 380mm (F) and 350mm (R) PCCB rotors. Both 997 GTx gen 1 and 2 cara have exactly the same PCCB systems.

Gen 1 GTx cars have smaller steel rotors than the Gen 2 cars, which have 380mm front rotors.

How reliable are Porsche ceramics?

Guy on Rennlist has 300,000 miles on his original ceramic discs and does between 6 and 10 track days a year too. Post one is a pic of the speedo and post 14 is a list of all that has been replaced on the car

I have read some good things about these brakes for guys thinking about retro-fitting ceramics - from memory the discs can be refurbished. I am sure they are not cheap, but maybe a better option than Porsche discs

They can be re-ground should they have a surface defect. And yes, they're expensive (but should be more durable than the original PCCBs)

Thanks, how expensive as opposed to the Porsche £3000 per corner?

So let me get this straight:

Cost of Ceramic brakes on a new 911 = £6k or thereabouts
- with normal road use, these should last for the lifetime of the car (150k miles plus ??)
- Discs should only need to be replaced if damaged?
- Pad changes required as 'normal'? (are the pads changed with similar frequency as pads for standard brakes, and are the pads the same (or similar) price?

Standard brake discs would be changed every 20-30k, so you would need 5+ disc changes over the lifetime of the car, which would cost more than the PCCBs in the first place.

Plus of course the obvious advantages of lighter unsprung weight, fade free braking, reduced brake dust etc.

I hadn't previously considered PCCBs for my next 911, but there appears to be good reason for doing so.

I note that PCCBs don't seem to command much of a premium on a used car (compared to the £6k new cost, let alone the £17k replacement cost) - is this because of problems with the Gen I or Gen II versions which have hopefully now been ironed out.

Might Gen III versions become more desirable on a second hand car if they are 'proven' to provide all the advantages and minimal disadvantages originally promised??

Conversely - if you or a hapless mechanic were to chip a disk changing wheels there is a £7k+vat bill for someone for a new pair. PCCBs carry little or no second hand premium, so if you get out of the car and sell it on before you need to change the disks then you have basically blown 6 grand. If you don't track it, would you really gain much from the benefits? If you do track it then say you go sideways into a gravel trap and damage the disks - kerching. If you track it and use the brakes as they were intended then you could kill them rapidly. The last I heard the record was only 6 track days, though obviously cautious brakers have been known to get loads more (especially on the right circuit, such as the 'ring). If you get a PCCB car and need to replace them then you can elect to switch back to steel. Though if the car is in warranty that will have to be a complete OE parts conversion (depending upon model you may have to replace the callipers for example) and can readily cost thousands more than just the cost of steel disks. Or you can opt for aftermarket steels and discard the warranty. Opinion also varies about the level of initial bite on them when cold, though most people who spent ~£6k speccing them generally rank them up there with sliced bread.

All of which is essentially why PCCBs carry little or no 2nd hand premium (dealers always try to wash over this point). They only really make sense if you are using it strictly for normal road use and expect to keep the car a very long time.

Didn't I read somewhere that the high cost wasn't just material and manufacturing, but they had to be assembled asaunit with different weight hat fixings as you couldn't shave the ceramic to get them balanced?

Or maybe I dreamt it.

That only added to what are expensive items to manufacture.

I ditched the ceramics on my GT2 and put these bad boys on....




...anyone after a cheap set of ceramics (perfect cond) email me....

What are they?, prices?
