Brian has one original of the 4 that was machined dramatically off center. I think the tire store put about 4 ounces of weight on it and I had not noticed before I saw that. So they're probably better than that.
He also told me that when he was in engineering school, which was right around 1980-84, in some class one of the profs was cutting apart current aluminum wheels (likely some snowflakes as aluminum wheels were pretty rare overall) and showing the class the voids and stuff in them. Fortunately, 40 years on, we can say yes they've held up fine and they proved to be reasonably safe and fit for use. I mean except for the off center one.
We had a big discussion on here about how they're centered, and trust me, I looked, the original ones can only be hub centered. There's no other way. The new ones could be built in such way that they could be lug centered, and if they are, you need to stick with their recommendation on lug nut shape.
