Guys I just got some wheels and they are 66.6. Has anyone purchased hub rings off of ebay I need aluminum ones and I need to know where I can go to get a good set I need to go from 57.1 to 66 .6.

in my experience, plastic is better than aluminum for these. They last longer and never get stuck.

Agreed plastic is the better choice

Really? I thought the metal ones would have been better. I will try the plastic ones first. Is there a good place to get them or is ebay good.

I've had the opposite experience with hub rings. I have always run custom wheels with every car I've owned since the mid 80's. Plastic rings deform over a period of time and you have to replace them every so often. The aluminum ones do not. I've run the same set of aluminum rings for almost 10 years on my D2. I had to have them custom made back then for about $100 a set including shipping. The only thing you do is use anti-seize on the hub so they do not "get stuck."

I'm just curious, the 57.1, that a A8 "Hub Center Bore" and the 66.6 is that like a MERCEDES BENZ wheel? I'm really just curious as to what vehicle, that's from. Thanks

Mercedes has always run a 66.56mm center bore. Audi has run 57.1 but D4 are 66.6. I think Audi is moving toward the 66.6 hub bore. Most wheel manufacturers made the hub 66.6 so it would fit both applications.

Started with the A5 and on to Q5, and then rolled back through A4, D4 A8, and C7 A6. Audi never really explained the "why." but the bearing was probably growing in diameter at the same time on the other side of the hub face.
