As the title states, do you guys know(for certain) what the center bore is? I have seen 64, 65.8, 100.6 etc etc. Does anyone know for sure what it is, and if possible the proof to show it is correct? I need this info to be correct because I am getting wheel spacers, and they need to know the correct center bore. The place that I called(wheeladapter.com) which I heard tons of good things about, those guys told me 100.6 mm bore, but then I searched on this website and someone said 65.8.
