After tightening to fix the rim lock, the thread groove on the inside of the nut was scraped and it became useless. I firmly fix it with another nut, and I think that it is good if it is decorated from above.
I attached it to a bead stopper that is not brand new (with rust on screws). The effect of preventing rusting is not known because it has just arrived. It is a place I want to avoid increasing the weight of the vehicle, but since it seems that there is no influence on aluminum, I give priority to fashionability UP. It is conspicuous, but it fits well with the gold rim and it feels pretty good.
