All 20 clamp nuts arrived on time and were in good condition. I installed and tightened each to 120 feet with no problems. A week later: all twenty were checked and all twenty were still firmly seated on the rim. Oh sorry, did I forget to mention how good looking they are? And remember - before I bought these nuts, I was thinking about buying a new car. It looks like a set of JDM Ultra-Premium Chrome Nuts is all I need to lovingly re-acquaint myself with that new car feel - guess! Thank you ABN!
