Grant is correct !!!

I have an old set of "PRIME" wheels ams the centers are about VW size. I
has always fighting an "out of round" problem with them. Prime did not
make "hubcentrics" for them, so I had a set made to match Miata, The out
of round problem is gone !
Plastic or Alum. ???? , just get them and use them. They will locate
the wheel properly as you put the nuts on.
