I have a used set of Black Volk wheels nuts and Locking nuts available.
24 pieces in total i.e. 5 Black nuts per wheel and 1 Locking nut per wheel. (obviously you would only use 4 nuts and a locking nut - before someone comments)
These are off my GTR so are compatible for all GTR's, I have the fitment info and will post when I get home.
Dum spiro, spero
