nuts to say the least! They are amazing. My car ('05 Dodge Magnum) came with two-piece nuts that failed quite often, and some spots on the tires won't touch your car if the nuts are a mix of good and broken. Broken in this sense means that the outer "skin" has come off the nut. Dodge also charges about $8 or $9 for a nut, so it gets expensive to replace. This is a solid build and they don't tend to fall apart like their two piece counterparts. I hope I changed the nuts!
