The Gen III PCCBs are fine for track work.

Most of the trepidation people have with PCCBs for track use comes from the Gen II PCCBs.

Overpriced Porsche option and 100% depreciation, but nice.

Have fun:

This is exactly what I have heard.

It's funny...ask Porsche and they will say PCCBs for track...and ask track guys and they'll say No Way PCCBs for track.

Which is it?

Both, and depends on the speakers' objectives.

For Porsche it's profit maximization.
For owners it's cost minimization.

What Porsche is effectively saying is: "take PCCB to the track and pay us a lot and often".

AP knows that the people who know of him and listen to him can't be hoodwinked. So he's truthful.
The official Porsche language is quite different, for instance this (https://www.porsche.com/usa/models/911/911-gt3-models/) :

PTS-BRG

PCCB are better in every way, and I mean without exception everything about the PCCB are better than steel.
Stopping distance, time before brake fading, overheating, rolling weight, rotor surface area, frequency of maintenance, lack of brake dust, no rust, ...
The only thing keeping everyone from choosing them is price/cost. If you can afford it or dont mind paying the premium PCCB is the better brake.

That's a little overboard, STG.

1. It's a consumable (albeit a LONG lasting one, unless you track it or get a rock chip - unlike tires which will have a much shorter life) so you shouldn't expect to get a lot back.
2. Some people prefer PCCBs over steels for various reasons. Therefore it isn't 100 percent depreciation if it makes one car more desirable over another (and carry a slight premium).
3. No Carrera option has zero depreciation. You always lose some money on options. (Exception - extremely rare and desirable packages like the PCA 60th anniversary GTSs, although even the 50th anniversary cars started depreciating below MSRP a year or two ago or so.) PTS maybe. depending on the color.

If they are questionable why are they standard on many of the most expensive cars. Seem hard to argue they are the best just expensive.

If you can afford them, buy them. In hindsight, I wish I had.

Porsche's spare part pricing is absurd, always has been, and has no correlation to reality or the cost of the option from the factory.

Sure...I would take PCCB's if cost was anywhere near realistic. They seem great.

But 20K for 4 rotors plus pads? Seems like more of a liability than an option.

There will be some point in the car's life where the cost of the brake job will exceed 50% of the value of the car. I guess if Steel retrofit rotors are available that is a fall back.

A GT car may be a different story.

STG

Don't believe any 911 Cup cars or track cars ever use PCCB. Never seen them on a Cup car.

What would take rate be on them if they made as much brake dust as the steels?? Seriously?

Is that cost related or performance related. No doubt expensive but a Porsche is as well. Think about an oil change. My Jeep is $35 with synthetic.
