Going to answer my own question here -

I called QA1, learned that the street version is a stock ball joint with polyurethane bushings, and the race version is a delrin bushing with their low-friction ball joint. Both versions retain same geometry.

All the arms come with coil-over mounts installed, with an optional stock coil spring mount available for around $69 retail.

These are all made in Minnesota.

So there I have it!
