Does anyone know the diameter of the center bore of our wheels? I'm ordering a pair of custom wheel spacers and they need to know the bolt pattern (which I know), the stud size (which I know), and the diameter of the center bore of the wheel, which I believe is also the same as the diameter of the hub lip that the wheels bear on. I think I saw somewhere before that it's 3.42" which is also 85mm. Can anyone confirm this?
