You got it correct.
This is a known problem with all cars and after-market wheels.  The stud is 
suppose to thread into the NUT portion.  This reduces all the forces on the nut 
to compression acting through washer onto wheel flange.  What you had is 
tension between shank and head of the lug nut.  This is the weakest part of the 
lug nut and it broke.  Lucky it didn't happen in a high speed corner.
  Its not very hard to replace the studs.  I believe there is a corvair stud 
that is a direct replacement, but longer.  I use a "C" clamp, socket and 
hammer.  Put the socket or piece of pipe over the inside head of the stud and 
clamp the stud/nut and pipe with the clamp.  Smack the clamp with the hammer to 
add additional force and the stud should start to push into the pipe.  Sometime 
I do two at a time (opposing stud on the same wheel), then install the new ones 
part-way.  I then re-install the wheel to draw studs into place.  Hope this 
helps.  Check that the stud doesn't bottom inside the nut.
