Borbet Hub Rings?

[dinanm3atl]

I want to buy these wheels just to roll around on but the backside of the wheels hub is not the chamfered(sp?) style of the BMW hub. It is a 90 degree cut. PO had them on his E21 so used 10mm spacers that had this as part of the spacer but won't be proper on the E30. 15x7 et25 is the E30 fitment to run 225s.

Where does one get the hub rings for these wheels?

My Borbet type Bs didn't come with hub centering rings. My local "custom" wheel shop had a set made for me. I would try a place that sells a lot of aftermarket wheels and tires.
