I've been attending more track events than planned when I purchased the car and am quite concerned with wearing through the Carbon Ceramic rotors included with the PCCB's.
I've searched to the best of my ability here on Rennlist and spoken with a few others familiar with the subject, but haven't yet found an economical option for new rotors.
Is there a relatively "bolt on" option to keep the existing yellow PCCB Calipers but use replacement steel rotors?
In hindsight I would've not purchased the PCCB's from the factory, but hindsight is 20/20.
At this time we're not planning to do AP Racing iron disc replacements in the 991 GT3 410/390mm PCCB size. We have/will have the following racing discs that mate up to stock calipers:
On sale now:
991 GT3 iron Front (380x34mm)
991 Turbo iron Front (380x34mm)
In final testing/production...on sale soon:
991 GT3 iron Rear (380x30mm)
991 Turbo iron Rear (380x30mm)
997 GT3 iron PCCB-replacement Front (380x34mm)
997 GT3 iron Front (350x34mm)
997 Turbo iron PCCB-replacement Front (380x34mm)
997 Turbo iron Front (350x34mm)
997 Turbo iron Rear (350x28mm)
996 GT3 Front (350x34mm)
996 GT3 Rear (350x28mm)
For those who are now reconsidering the PCCB'st on their 991 GT3, don't give up hope. We're looking into possibly developing a complete caliper & disc kit using AP Racing's latest Radi-CAL technology. “Radi-CAL” is a blanket term used to describe AP Racing’s patented asymmetrical brake caliper design. Radi-CAL technology is grounded in Computer Aided Design (CAD) and Finite Element Analysis (FEA), and allows for organic, alien-looking designs that are a radical departure from conventional caliper designs of the past. Calipers leveraging the Radi-CAL design philosophy are widely considered the pinnacle of current brake caliper technology. Since their inception in 2007, these revolutionary calipers have amassed a lengthy string of race victories at all levels of professional motorsport, while redefining brake performance expectations.
We all know that the PCCB's offer a significant unsprung weight reduction. That's their single most valuable attribute if you track your car. The goal with our setup would be to gain back as much of that unsprung weight savings as possible while using the lightest racing components and the most durable iron discs available. In other words, we would use the latest technology to solve the brake issue via efficiency rather than brute size. That means extraordinarily lightweight calipers, and slightly smaller discs that are far more effective at cooling. Some features of such a setup would be:
On the front, my hunch is that our complete front corner would weigh very close to what the complete PCCB front corner weighs.
The one on the left would be the rear, and the one on the right would be the front.
Here's what a 25mm thick pad looks like vs. an 18mm thick one. The OEM pads on the 991 GT3 iron setup are 16.6mm thick for reference.
Such a setup would be a professional-grade endurance racing setup. For example, the components would have technology comparable to what we've used to service the factory Corvette race cars (C5.R, C6.R, C7.R) that have won Le Mans numerous times.
Target pricing for the complete front kit would be in the $4500 range, and the rear would be similar. Total cost for all four corners would be roughly $9k.
Please don't anyone freak out just yet...these won't be ready tomorrow. A lot must be done before we can make this a reality. We're just beginning to sink our teeth into this one now. That said, the more interest we see, the more likely we are to make this project a priority! We aren't interested in rushing out a half-baked solution. If we do it, it will be done right and the absolute best brake system available.
So who wants one?!?

Do you carry Endless Brake Pads? Do they have pads for 991GT3 and RS?
So I guess Porsche decided to use "the have to remove your calipers" to make pad changes. This is obvious in order to boost dealer service dept revenue....orthojoe is my hero...I find it funny people complain about hard water spots on their center lock bolt...
Joe's show actual wear and they look great !

Wait, it looks worn? Lol!
The calipers shown above from Essex look legit. I dream of swapping pads within minutes like I used to....
Doesn't racing brake have a steel rotor replacement for the carbon ceramic rotor ?
Yes, we are shipping them since February and plenty in stock - Front and Rear
Front:
410x34mm (Replacing stock pccb 410x36)
28.42 lbs
Rear:
390x30mm (Replacing stock pccb 390x32)
21.58 lbs
They are made from a metallurgy developed by RB in the past decades. Rotors are built with Center-Mount and Open Slot patented designs for improved braking performance and longevity.
A very affordable package for track racing as well as street driving while preserving your pccb for future resell value.
Black braking surface is now our standard finish to assure non-brake pad contact area remains fully protected from rusting. And they will look much more appealing after just a few stop like this:
