I'm not sure it's safe to say Gen 3 PCCBs are bulletproof on track. Over the course of a year and a half I wore out a set of rear pads and took the rear rotors down to under 40% density on a GT4. Front pads and rotors were at 80% after that same period. I believe it came down to my driving style (got into the traction control too much) while running some double sessions at Laguna and Thill. When you get too much heat into them is when you get excessive pad wear and rotor degradation. I know some other GT3/GT4 guys that are running them on track extensively that tell me theirs are doing fine so it really comes down to the driver style and conditions IMHO. I have to say PCCBs on a GT4 may be the pinnacle of braking excellence on a non race car.

Latest rotor $$. This is for ONE PCCB rotor.
Steel rotor. In the entire LIFE of a 991, maybe get changed what, 5x over life of car??
Ceramic rotors will need to get changed likely sometime in the life of the car. Whether damage or wear. Likely one time.
Still, I like the PCCB's and would order them .... just noting the facts.

Maybe not. I drive no more than 6k miles a year. After a decade, I expect to have roughly 60k miles. If the PCCB rotors truly last 100k - 150k (street use only) then in a decade they would still have a lot of life in them. Only time will tell!

The cost of ceramic rotors will come down over time. If you are thinking about ordering a new 991 today, then by the time you get 100k-150k miles, in say 10 years, I think it's safe to assume the ceramic costs will be a lot lower. For one thing, there will be a lot more cars on the road with ceramic brakes. Another thing is just tech innovation. Already, the cost has come down vs. the Gen 1 brakes.
Note that the cost per rotor at SunCoast is now $5300, not $6057 as reported above.

Has anyone compared the weight of the standard black calliper rotors with the ceramic rotors? I've heard that the weight savings is 16 Lbs. vs. the red S callipers, but have not seen weight data on the black non-S rotors.
The weight savings will be less, of course, since the black rotors are smaller and the callipers also look smaller and lighter.

Which cars had which generation of PCCB?
I assume that the 996 cars had Gen 1. Did Gen 2 start with the 997 cars, or the 991 cars? My assumption is that the 997 cars had Gen 2, and that the 991 cars have Gen 3? Or is it still Gen 2 on the 991 cars?

Gen 3 on 991 cars. Both .1 and .2

Weird, I know.
I mustve been dropped as a baby. Twice.

Also, rotor cost will drop over time. In 10 years it won’t cosf $20k to buy 4 ceramic rotors. Just like other technologies cost a lot when new, economics of scale and improved manufacturing cost will lower the price.
I don’t follow the argument that Porsche is promoting them to make money, when they charge ~$7500 for the entire PCCB option and SunCoast charges $20k for the rotors alone?! Yes, the cost of the steel rotors needs to be factored into the Porsche price, but it’s hardly a high margin item.

In 10yrs time this version will be old news, dated and not even being used then. There will be no economies of scale. Just a costly part. There will be new and better tech and probably better priced.

Right, so you buy the latest version of PCCB in 10 years. What’s your point? My point is that ~$7500 for the PCCB option is not that much if you plan to keep the car for 10+ years, and you shouldn’t assume a $20k rotor replacement cost at that time.
