These are really hard to find. I just bought a used single cap forr $20 last week. In case someone needs them:

Can someone tell me if this is the correct style for the rare 15" BBS wheels for our cars? I thought they were just round and not dimpled like these are, but I can't find a good pic now to confirm. I need a set of caps for mine.

That is the ones, they are definitely dimpled.

Hmm, I always thought the original ones were round like the ones on the stock 13" basketweaves. So these are the caps I should be looking for then? Because I know of where to get another set like these, but I want to make sure I get the correct ones or I will be pissed! :)

Your previous thought is incorrect. Those are 1000% factory correct for 15" BBS RA's.

Cool, thanks Layne! :thumbup: I guess every pic I saw of these was from a distance so it was hard to tell.

Oh and I am still trying to find that ad for the wheel. When I find it I will scan it and show it to you.

Those are exaclty like the ones I have on my RA's also. It is hard to tell but they are in my sig.

Anyone know the diameter of the holes those go into on the RA's? 48mm Sound right?

same here too.

I measured the once and I believe they are 60mm but I can check this afternoon. It is about the same diameter as the OEM 13" wheel stock smooth ones. In other words, if you take a stock one and turn it around backwards with the mounting part facing out, you can fit it in the hole.

Just confirmed, 60mm (I forgot I drove it to work today and it's sitting just outside my office)

So does anyone know if back in the day you could get BMW caps to fit these? I think that is maybe what I was getting confused about? These have the BBS logo on them so they are BBS's own caps not BMW's. I kind of want to run put the Roundel on these when I get them, but I probably shouldn't. I wouldn't want to ruin the BBS logo that is already there.

The BMW stick-on roundel for the stock caps fits perfect. One of mine had one on when I bought my BBS's

They are BBS caps, and they came with the BBS logo on them. Many owners/delaers/whoever put the BMW roundels on after the fact.
