Post #2 in the below thread shows the two types (they look very similar to the ‘untrained’ eye)
The first one (part number) 9965 98 7070 are the forged BBS alloys you see on most ND’s with factory BBS wheels (RF launch etd; current Homura, GT sport tech from a few years ago etc). These are pretty expensive- an easy £700 a wheel. Try calling your Mazda dealer parts dept for a price idea
The second version (part number NA1V-V3-810 ) in the photo in post #2 in the link above, are the BBS alloys off the Z sport special edition, circa 2018 (the cherry top ND in machine grey).
These are a LOT cheaper in price. About £250 an alloy. The part number is under the pic.
Here they are from another site:
