The wizards at either PCNA or PAG seem to have "secretly" removed PCCB (changed to iron) from some GT4RS builds after being switched to model year 2023.  I'm aware of one that arrived recently at a dealership that caused quite a surprise when the expected yellow calipers were observed to be red.

The GT4RS PCCB parts seem to be the same as 992 GT3 fitments (photo from eBay).

Whoopsy, how did your GT4RS build turn out?
