Mk88

Above is the PSCB brakes after less than 3,000mi of highway driving and 3-4 track days. The brake pad wear indicator is on. My plan was to replace the pads, only to find out Porsche made these PSCB pads proprietary and there is no aftermarket alternative.

Instead of replacing brake pads every 3,000mi, I want to save some time down the road and just get rid of the PSCB. Can I simply unbolt the PSCB rotor and put on OEM cast iron rotor instead?

I want to reuse the PSCB calipers as they seem to be the same as the base 6 piston front /4 piston rear calipers except the paint color.

reach out to the braking vendors. Race Technologies (Brembo), Giro, PFC, etc. See what options they have for fitment. I could swear these are larger than the standard rotors.
I think this is it:
cast: 360mm
PSCB: 410mm
PCCB: 420mm

So you'd need a retrofit rotor + pads of the proper diameter, annulus, and offset.

Even if you found an after market solution I don’t think they’ll be much better because you’re dealing with a very heavy car. Not only will brakes wear out quicker I wouldn’t be surprised if replacing suspension parts occur more frequently as well.

you are actually right
