Okay, this set of studs and nuts converts our OEM wheel bolts, to a more conventional lug nut configuration. The only caveat is that these are for a set of BBS wheels, and if you look closely they are not the same taper seat. They have a rounded seat, the nuts. That may be a feature of BBS wheels, I have no idea! They are also all the same length, not the long and short of our OEM bolts. $250USD OBO. I sold the wheels.
