    Hub bore size A6 C6?

    Guest-only advertisement. Register or Log In now!
    I've done some digging and am getting mixed results.
    On our C6's, is it 66.6mm hub size or 57.1mm?
    Shopping for wheels and am trying to avoid needing rings as I've had bad luck with them in the past.

    Thanks

    Our hub bore is 57.10mm. What "bad luck" did you have? I am running aluminum Hub Centric rings (purchased from ECS) on my wheels and have no issues.

    Bought some cheap plastic ones before that fell apart.
    I'll just order the aluminums from ECS.
    Thanks for the info.

    Not to thread jack, but I'm going to be taking a look at set of 19's off of a C7. My understanding is that the hub bore on the C7 is bigger (66.6mm) so I would be needing hub centric rings. Anyways, the ones I found on ECS are plastic and after reading the above posts, I'd want to go the safe route and get better quality ones. I couldn't find aluminum ones in the section that I was looking under "hub centric rings". Any assistance would be greatly appreciated, thanks!
