One of my donor mini hubs has this "erosion" around a couple of the wheel stud holes - a shallow groove around the hole - probably from being run with loose lug nuts? Anyway, I noticed it when I cleaned & painted them up and was getting ready to install the new races. Befroe I drive them in, is this OK? I'm planning on running stock rims, I'm having second thoughts as to whether this will cause problems with lug nut loosening or anything else. Is this common? Are they useable or should I scrap 'em, or MIG a little bead in there and grind it down?
