I spoke to Craig (rennstore) about these Green pads (P50). They're a very hard compound similar to the Pagid Grey (RS-15).
I decided to pass on them and keep using the RS29, and replace them as usual. The RS29 and RS19 are very similar, but I like the initial grip on the RS29 better. I prefer to use a softer pad and replace it more often, than using a harder pad that will put more wear on the rotors.
When I calculated the proven 10,000 track miles from the PDE PCCB rotors on track days, the number got close to 80 track days. This is in line with PCCB Gen II lasting up to 6 times more than the cast iron rotors. Although running cast iron rotors is cheaper, most of the GT3 street car owners don't get to see 80 track days with this car, so PCCB are more than fine for combined track/autoX/street use.
There is a 3rd generation line of CCB by Brembo that has not yet reached the market for OEM but they're available. Unfortunately, the cost is higher, but they weigh half as much as the current PCCB. The full brake kit can take close to 90 lbs off on unsprung weight compared to the standard GT3 brakes, and close to 50 lbs compared to the PCCB brakes.

Thanks for the info. I have some specific questions about PCCB and might PM you when my 997 GT3 PCCB conversion kicks off. I'm working on finding a set of "take-off" brakes at this time.
Thanks!

THAT IS COMPLETELY TRUE ! PCCB for track usage is the biggest marketing scam ever from Porsche... and The Turbo says "here we go again" because this forum is full of treads related to the issue:

Moreover, the line-up of 997S being used at the Porsche Driving Experience with a multitude of instructors and students were all equipped with PCCB.
You may not know that there is a race series called the Porsche SuperCup, where they run the same PCCB rotors we get with the street cars. Real racers and race cars on Formula 1 racetracks in all kind of conditions, not the average lapping day kind of driver.
Nissan, Audi, GM, Ferrari are releasing cars equipped with the same CCB rotors technology. Porsche took the lead on offering these brakes on street cars back in 2001, and now other manufacturers are following.
This is hardly a marketing scam. They work, they last much longer than cast iron rotors, yes they're expensive.
My PCCB rotors have 39,000 miles, 66 track days on my two GT3, unknown number of track days on the German Tuner and owner of the wrecked GT2 I bought them from back in 2004, unknown number of track days on the second owner of my first GT3 until I bought the PCCB back from him 6 months later. Front ones are due for replacement, rear ones are in perfect shape. Generation I rotors that are not as good as Generation II rotors.

How can I neglect the benefits of PCCB ?
I had PCCB on my GT3 and they didn't last 3,000 miles. I have 3 other people I know in my region who had to replace them also. They cost 10x more than steel and last 4x less = 40 steel rotors sets equivalent. Not a difficult equation to understand...
The Porsche Driving Experience has unexperienced drivers testing car way from their limits...
You are going to say the same pretty soon... good luck !
