I thought about spacers but I'll loose about 1/2 inch for the lugnut to hold onto.... How hard is it to replace stock lugs with longer ones? Then use the spacers without the built in lugs?...
I don't understand why you would lose 1/2 inch for the lug nut when the spacer would go over you OEM thread and then the spacers will have their own set for the wheels. I could give you full spics to make spacers from motorsport-tech.
