I can give you the part numbers to try, but I can't guarantee it will fit.
The diameter and thickness are the same, but everything else I have no idea.

Front:
971615301D / 971615301R
971615302D / 971615302R
410mm x 38mm

Rear:
971615601J
971615602J
365mm x 28mm

Consider ordering online so you can return if it doesn't work.
You can get both those from Zimmerman afaik.

I have the normal steel ones (red caliper) with 21" RS Spyder allows - fitment should be the same across all 21" . I've not tried other Taycan break (maybe on test drive I did but can't remember).

I have PSCB's and they are smooth and like a mirror after 35,000 miles. I love the look of them, they perform great for me and basically no brake dust. Just like any part, battery, air shocks, electrical components, etc. there are going to be a percentage that are bad and have manufacturing flaws. In most cases the rotors should last a very long time.

I think the issue might be Porsche PSCB manufacturing quality, combined with the fact that brakes are considered wear and tear item so it's hard to prove whether they are experiencing a manufacturing flaw or are just worn out.

You'd think that should clearly point to a manufacturing defect, how else would you wear out one side of the car only? How old is your car? Is it still under warranty?

Car is 5 years old out of warranty.

Exactly the issue I see here. If it carries a higher risk of failure, and then it’s deemed wear and tear when it goes bad, is it worth it? I mean, $1K out of pocket ain’t much, but I think these run into high 4 digits to replace.

More like 5 digits; because the mechanic ain’t free :)

Is it not the case that 21" wheels fit PCCB, PSCB and steel?

Nice picture!

To answer your question, I think you are correct, those wheels will fit every brake disc type.

Would help if you quote the post when replying, your statement standalone made little sense.

Any 20" Taycan wheels clear any Taycan brakes, obviously there are zero issues with 21".
