I've got these old Borbet wheels. I believe they should have four hubcentric rings, so I need to i.d. the wheel then find some rings. What are they?
Two of these remain.
I only plan to use these to get the car in and out of shops so won't be driving it too far or for very long. But the last time I drove it up from NC with these wheels it shook like it was about to come apart.
Can you identify these Borbet wheels? Can you suggest where to find hub centric rings to fit?
Old Borbet wheels have the correct hub for the E28. The wheels that came out after the E39 had the larger hub bore requiring the rings.
Early wheels had numbers that were appended with a /0 to indicate the larger bore. This was true for the type C.
You have type E wheels. Looks like they were made in 95 so I have no idea if they need the rings or not. But if you have rings in two of them, you need the rings if the ring fits your cars wheel hub.
You don't need to know the wheel to get the rings. All the rings for the E39 fitment to E28 adapter are the same size. The drop the 74.1 to the 72.whatever.

I have these wheels on my car. They use 74.1 to 72.6 hub rings. There are several sets on ebay right now with a wide range in price. Here's the least expensive. They are what I bought, and work just fine. You can go with more expensive polycarbonate or metal rings.
Word of advice. They are very thin. Be careful when you install them that you don't inadvertently let one slip off at an angle. When you torque down the lug bolts it will crack.
If you tighten the lugs slowly and gradually you can for the most part eliminate the need for the rings. Especially if you're only going to be using them for a short time. You can also wrap aluminum tape around the hub.
Yeah, jc72 beat me to it. What he suggested is perfect.
I have Moda M1 wheels (in the pic). Oddly, some of them require the hubcentric rings and some don't. It's completely obvious when they do -- the rings can fit flush into the wheel, but I place them on the hub first, of course.
And metal (aluminum), not plastic. Tire Rack once sold me that plastic crap that breaks immediately. Never go plastic.
