Proper lug nut??

looks like they were used with acorns (or they are made like that for easier shank nut installation) WRONG APP!. Normally if the center is steel, you can run an acorn 60 nut, but if the center is AL like these composites, you need a shank nut as AL is softer than steel and an acorn will lose torque over time (and most likely will damage the hole). There is a washer recess for using shanked nuts. Use proper shanked nuts for a more uniform look.
