A Google search led me to this thread today (was searching for E30 and BBS cap fitment - there's a local Bimmer owner trying to buy my spare caps). This is an OLD, dormant thread - but just in case anyone else stumbles across it like I did:
- YES, the centercaps from Mazda's 14" and 15" OEM BBS Miata wheels are interchangeable.
How do I know? I own both (using the 14s as my winter wheel, 15s for summer), and I use one set of caps on both.
- And YES, the centercaps (not the wheels, just the caps) from Mazda's RX-7 BBS will fit on OEM Miata BBS wheels.
How do I know? Again, I own both. Perfect, snug fit. In fact, the part #s stamped on the inside are identical.
Hope this insight helps someone down the road! :icon_cheers:
