Lug Nuts - Muteki, Kics, Rays, and Work
Not sure what they're called. The Formula Lugs are two-peice lugs. The main lug, then there is an aluminum "cap" that screws into the lug. They're like open-ended lugs, but there's a "cap" that screws into the open-ended side. If that makes sense. Basicly, if you look at the pictures of the Formula lugs, the colored part (red, blue, or black) is what I am calling the "cap."
