yea I posted that up like a month ago, I PMed the guy that was selling them and he said

"hey wassup, i don't have any 16" right now. these rims were made
for a friend of mine by a mfg as a special request. i don't
believe 16" versions will be out for quite some time. the rims are
pretty hot looking though, very sweet oem look."

Here is the link to one of his auctions... although I am sure you already found it since you posted up the pictures
