It depends. I think an 8" wheel fits with the right offset, but I don't know how big those are. What is the offset on them? If it's off in the right direction, you could use an adapter to bolt on the BMW wheels, but it would need to have just the right offset - unlikely. You said you could get a great deal on them, so I'm assuming this is about cool wheels at a great price: it would be cheaper/easier to get 4x108 wheels than mess with this, unless the offset is just right. If it is, then you could probably use an adapter to put them on. Get all the numbers and post again - you might be lucky!
