13" PBR rear disc brakes

I saw flyinbye has 13" rear PBRs. Are these any different from the 11.6 or 12in ones found on Fbodies? Are they a big swap from factory thirdgen pbrs? Trying to justify these beyond the "mines bigger then yours" line.

Since the same PBR calipers are used (1LE/LT1), I assume the difference is rotor and backing-plate size. With OE's in place, I'd have a difficult time justifying the cost.
