Center diameter

Hello all,

What is the wheel center diameter for G01? 66.56 or 66.6? Can we use both sizes?

Thanks

Barry

66.56.

Depending on the tolerance, products could be substituted.

I found that spacers with a 66.6 CB were slightly “loose”. BMW claims a 66.56 CB, yet H&R spacers for our cars have a 66.5 CB, and fit PERFECT! Figure that one out lol.

Can we use wheels with bigger CB? Can the bolts centralize the wheels (like another type of wheels using nuts)?

Sure you "can", not a big deal, but hubcentric rings are highly recommended anytime you use a wheel with a bigger center bore. I wouldn't bank on using the wheel bolts to do anything other than what they are designed for, and that's holding the wheel to the hub. The rings do the centering.
