PCCB rotors from porsche are effectively lifetime unless you track the vehicle - they only 'wear' if you get them really really hot which requires extreme driving…
No, I completely agree with you.
Thanks for sharing, it's an interesting example of hard data that Porsche apparently feel inappropriate to make easily available....I snapped this photo from a Porsche Taycan presenation last week in anticipation of this frequent topic - it documents how regen behaves in the various settings for Taycan - this porsche factory information and therefore not subject to debate

Which only matters if you ever use launch control. Personally, I've had different cars with Launch Control, including my current Taycan. The only time I use it is some time before warranty expiration to make sure it still works. This is why I went for the Taycan Turbo over Turbo S. I also particularly did not want the electric charge port (blocks the air scarf vents, making them completely non-functional decoration, almost no different than a sticker vent some people put on their cars) and PCCB's - more susceptible to damage, expensive to repair, and require warmup before full effectiveness, which is even harder on daily commutes with EV recuperation. I did option RAS, I like it for parking lot maneuvering and u-turns (probably also useful for highway, but I cannot tell the difference, since I never had another Taycan without it).
If full power was available without LC, I probably would have compromised and gotten a Turbo S.
I disagree with that statement for one reason, at least at it relates to Porsche’s PCCBs. In my experience, owning multiple Porsches simultaneously, some with iron rotors and some with PCCBs, I found the feel of the PCCBs much better when trying set corner entry speed in the mountains from high speeds (ie dropping from 85-100 down to 25-40). I could be very precise in how much speed I scrubbed off with the PCCBs, much less so with the iron rotors. Additionally, once on a trip through the epic central/Southern California mountain loop, the iron rotors in my Spyder faded badly. Never ever had that issue with carbons.No, I completely agree with you.
The only place carbon/ceramics may be better is a race track.
I am not familiar with how good or bad road car composite brakes are but I was a pioneer of composite brakes in Formula 1 starting in 1982 and the development to get them good enough was hard and long!
Maybe good news coming. At my German dealership the tech guy mentioned that there may be a power boost coming soon (paid service via Porsche). Seems legit to me as aftermarket tuners also take this on, so why not Porsche within their control and making them some extra €.Which only matters if you ever use launch control.

PS> One of my pet peeves in the Taycan is the fact that Porsche locks the full motor power behind launch control which has to happen from a stand-still (vs. unleash the full power for highway passing speeds for example). IMO it should be available whenever the accelerator hits the floor. The only reason I can think of them doing it to limit its usage because it probably damages the battery ever so slightly every time a customer uses it, so Porsche would rather it was of limited use, to save on warranty claims.
I wouldn't pay for any extra power in LC. Might be tempted to give Porsche some money for unlocking LC power as boost power any time, depending how much they asked. Honestly though, I think they should provide it for free for all trims - convert it to Audi etron boost like implementation - up to so many seconds of boost power available any time.
I'd be curious if anyone has done any head to head comparison on a Taycan, same tires, same suspension, different brakes. I can see PCCB's having a bit more stopping power in an emergency due it its larger size, but PSCB's have the same size. I'd think on cold brakes, PSCB's might actually brake faster from 120km/h to 30km/h than PCCB's. PCCB's will probably do a bit better when warmed up, and be able to take more repeated heavy abuse before fading. I've taken my Taycan with PSCB's on spirited drives with occasional hard braking, no complaints about he brakes.
Me too. I assume that, once ABS intervenes, the limiting factor is the tyres rather than the brakes.
Also brake consistency when going fast for a long time is, IME, influenced very much by cooling efficiency and whilst Porsche brake cooling is way more advanced than some makers it won’t be a high priority bit of engineering where it influences cost and styling.
