I was concerned about ordering this product because some people complained that the adapter was too loose around the car wheel hub. As you can see in my video the play was negligible when put around the hub. I recommend applying a copper based anti-seize to the hub. This should eliminate the slight wobble. I bought a 57.1mm to 66.6mm adapter. If you wish to purchase this size please note that Audi/VW rims are either 57.1mm or 66.56mm. That's why I included photos. The adapter must not sit flush on the rim by itself. Don't worry, just take a rubber mallet and hammer it in place. It hasn't given me any problems and it solves the problem of people complaining about the adapter being too lost. This adapter turns out to be soft aluminum. It won't damage your rim if you push it in there. I tested my car at highway speeds. No vibration noticed. I definitely recommend this product. This is a great value and should last longer than those cheap plastic adapters.
