I guess I skimped through reading the whole thread where he is only looking for a 1/4" spacer
I think he is actually looking at 1.5" that are more like adapters with new studs an lug nuts. I don't honestly remember how we got on the 1/4" deal. I wouldn't go further than that on stock length studs, but they make them thicker. They can only make the other kind 1" or thicker because of the lug nut holding the spacer will hit the back of the wheel an keep it from sitting flat.
