My vote is #2. The Magnum wheel won't hit the wrong chord with any Mustang lover. Like Tork-Thrusts on a tri-5 Chevy they're never wrong, but they've been done to death. Wheels 4 and 5 look good, I like them, but they risk looking dated in a few years. The 427SC Cobra-style wheel has been sufficiently updated to not look retro, it has enough window area to show off the brakes, and it says Ford without saying you can't think beyond Mustang OEM equipment.
^ Nailed it.
My 65 Shelby clone will have real knockoffs reminiscent of the cobras... because they’re cool. 👍🏻
