Copy/pasted from JDM land, can someone confirm what material these lug nuts are made out of? I am hoping its either steel or chromoly. Reason I ask is because I dont like running aluminum lug nuts. Need confirmation ASAP thanks.

 

Last time I checked, they were aluminum. But, I could be wrong.

 

I honestly have no clue...But if it has a honda part number you can try calling your local honda dealer and asking them.
