Maybe almost the same wheel, but different BMW style codes...

As stated before, it seems that BMW changed some descriptions, P/N and nomenclature for the CSL wheels once the ZCP was offered. I do not know the factual reasons for those changes, I only know that
now both are Style 163, both rear wheels are exactly the same, and
most of the weight savings vs. the standard M3 forged 19" wheels were in the tires (almost racing tires) and less in the wheels.
