threads in bending are bad because the minor diameter is relatively small compared to the rest of the structure usually associated with a thread, and there is an abundance of stress risers due to the threads themselves. an in a lot of case it is cyclical and to some extent reversing, which is really bad.

But yeah, those are probably the only rod end based front uppers I'd seen for a miata that I would feel safe running. But I think I got a plan. I will be using the stock dimensions as I feel I can get a sufficient amount of caster with the NB subframe.
