Heim joint meaning an exposed metal bearing with a threaded rod. Like all the “racing” lower control arms.
Stock cars do not come with that style of joint on suspension. Lots of enclosed spherical joints on cars from the factory.

You are describing a rod end, not a "Heim joint", specifically. Rod ends are only radially rated, while spherical bearings are both radially and axially rated. Which I find even stranger, since the lower control arm is essentially a two force arm and only needs a radial rating, really. The axial load is handled by the toe arm. A rubber boot covering the joint doesn't change what type of joint it is, it just makes it a little more weather tolerant.
Or think of it another way; if you buy all your spherical rod ends from Aurora instead of Heim, what are they called then? Chances are, everyone still calls them Heims, the same way everyone points at a box of tissues and says "Hand me that box of Kleenex", even though they're made by Scott.
