They should work, the lugs that I ordered with my staggered set of wheels were exactly the same as OEM except they were silver. Other than that, same size and length. The only thing is that it is going to depend on which replacement wheels you go with as them may be a bit thicker so you may have to go with slightly longer lugs.
