These are very nice pieces. High quality stainless steel stampings with a highly polished finish.
Also, I would recommend adding a bead of silicone adhesive to the flat on the back side of the hub cap. The little fingers on our wheels were a little weak from the ravishes of father time. Adding the silicone makes me feel a little more secure about the hub caps staying in place while still making it possible to remove them if I need to change a tire or service the brakes.
