I originally bought aluminum nuts but was afraid that a few disassemblies a year would eventually break them. Then I thought of oblong steel nuts. So glad I bought them. Beautiful neo chrome finish, bold finish and forged steel! They fit well and look great! Remember to screw them counter-clockwise first so they're properly seated (feel/hear a click), THEN clockwise to avoid cross-threading on the studs. I love these elongated nuts! Must-have for aftermarket wheels!
