I'm not sure about the offset and bore numbers. I let the pros tell me what I needed.
I will say that when I first got them they had a vibration. I called the store and they shipped me out hub centric rings. After that no problems. They are centre mount rims
The company is called wheelplus USA. I found them on eBay. Basically if you search BMW 214 rims you will see them on eBay.
Not sure if were allowed to post phone numbers here so I'll pm you the number.
