Gorilla makes tuner lug nuts, they are also known as "SD" or small diameter, because the holes on 'tuner' wheels have a "small diameter" lug hole
The gorilla lugs all take the same key, which kind of sucks for security...(any locks can be broken off with simple tools also
)there are other brands that are the same small diameter but the key/splines are a different size. Shop around there are lots of options.
