    BMW wheels on Vette .. Bolt pattern question

    I would like to install a set of BMW wheels made by Beyern on a 2011 C6 Corvette Coupe.

    The question I have is the bolt pattern spacing.

    The Corvette has a 120.65 mm bolt pattern spacing, while the BMW has a 120.0 mm spacing. So, were looking at a difference of only 0.65 mm (.025") ... 25 thousands of an inch.

    I have read from other sources that these BMW wheels will fit and presents no problems as far as the bolt pattern is concerned. But, I have also read that it ain't a good idea.

    Does anyone have any knowledge of this ... Yay or Nay ?

    Thank's,
    Ron

    BTW ... Here is what the BMW wheels look like:

    jiveass ... Thanks for the link. Didn't sound like he had a bit of problems with the BMW bolt pattern spacing on his Trans Am.

    I think you'll be fine. There are some 04-06 GTO owners who run Beyerns. They are nice wheels IMO.

    GTO's run a 5x120mm boltpattern so they would not have any issues.
    I have run 2 different sets of 5x120mm wheels with no issues whatsoever but was also using hubcentric rings.

    I would recommend looking into some hubcentric rings.

    Well, like I stated before, the Corvette has a 120.65 mm bolt pattern spacing, while the BMW has a 120mm spacing. So, were looking at a difference of only 0.65 mm (.025") ... 25 thousands of an inch.

    I don't think useing "Hub Centric Rings" will be of much help. The problem is not with the Center Bore of the new wheels matching up with the Center Bore of the axle hub ... In fact, the stock C6 Corvette wheels are not even "Hub Centric" ... they are "Lug Centric" (the 5 wheel studs do the alligning of the wheel to the axle hub the wheels mount to).

    What is needed is something that will keep stress from occuring on the wheel studs. Like I said before, a difference of 0.65mm ain't much, but it is enough to cause stress on the wheel studs when the lug nuts are fully tightened.

    After doing some checking .... The solution is PCD Variation (Wobble) Lug Nuts ... These lug nuts can adjust to balance the difference in the bolt pattern spacing.

    Here is a photo that gives you an idea as to how they do this:

    (The photo below shows a PCD Variation Bolt, but we use Lug Nuts ... The PCD Variation Lug Nuts are also available, and operate the same was as the PCD Variation Bolt shown below)

    They claim that these can adjust up to a max of 2.4mm, but in my case, all I need is an adjustment of 0.65mm ... Piece of Cake!

    You could also look into ARP wheelstuds.

    It's not necessarily "recommended" but that's only because wheels are designed with the correct offset already. Is your wheel going to fall off? Probably not. But that doesn't mean it is out of the realm of possibility. Wheels can fall off due to any number of things like corrosion, stud failure, and incorrect stud length. That 25 thousandths of an inch is far less of a worry as long as everything is torqued correctly.
