Once upon a time, one of Chrysler's wheel manufacturers came up with a cast aluminum wheel design that drew inspiration from magnesium wheels used on mid sixties Cobras. It was called the Cast Center Road Wheel and was offered as an option on various 1969 Mopar models under Sales Code W23.
Unfortunately, at that time, aluminum casting was a recent innovation and the process still had some issues. Some of the later development tests would show that the W23 wheels had a tendency to loosen the lug nuts, allowing the wheels to come off.
