There was a buyer beware a few months ago about replica kics lugs you might want to double check u didn't get hustled
i noticed this before on my own personal car and a few customers cars before. i believe because of the exposed lug nuts caused the stud itself to rust and leave the rusty residue inside the lug. grease or antiseize the studs tend to help it
I believe this is been caused by those ugly wheels which are literally making your lug nuts weep in misery. Remove those wheels and sell them cheap now! I may be able to assist in taking those off your hands. For a fee of course. :wink:
I purchased genuine set for my gtr and nsx and not a sight of rust.
Good chance they are replicas
