Has anyone run bassett wheels?

I know bassett wheels are big in circle track racing among other things, and I stumbled across these. They seem pretty lightweight (for steel wheels), the price is right, and they're made here in the USA. Does anyone have any experience with these?

No experience, but they look a whole like like Cragar wheels. I checked and they are a "whopping" 3 pounds lighter, and it looks like most of the mass was taken out of the center. I wouldn't trust them for wheeling myself just to save a few pounds when they cost a little more.

idk if i would trust them either. had a customer bring some in that were on his circle track car and he snapped the center right off. seems like a red flag to me

It also says they require 45 degree lug nuts... I am pretty sure conical seat lug nuts (like we would have stock) are 60...?
