Be careful with the term OEM. It has been abused to the point of uselessness:

In your case you thought you were buying OE 334 wheels, right? Do you think BMW allows their OEM supplier (whomever that is) to make direct copies of their style and sell them in competition to BMW? IMO, No. But perhaps they do....

So what you have is a wheel mfg that once made a wheel for a car company- maybe BMW, maybe Daihatsu..they are therefore "An OEM" or a MANUFACTURER of OE wheels. Now they copy the BMW wheel, say "it is OEM" and they are, in fact, correct: It is a copy of a BMW wheel made by an OEM, therefore they call it OEM.


Finally, your last comment says that the seller has confirmed that this is OE, not OEM. Very different things.

I don't care where a wheel is made, I want to know the company bearing the legal responsibility for the quality within that wheel has such DEEP pockets that they will ensure the quality is there to protect THEIR pockets (and my life).

In this case, if indeed they make the OE and "OEM Copies", does dicastal have the same process in place for their OEM as their OE products? It would be interesting to know.

Not sure the discussion helps you answer your question, but wanted to comment.
