My experience with the Mustang's MacPherson strut front suspension on late-model classic variants: the strut design is lighter than the double-wishbone but offers less geometry adjustment. For a street car, it works well. For a performance build, the limitations matter.

The aftermarket has addressed this with aftermarket strut housing designs that allow camber adjustment. For the Fox body Mustangs, the aftermarket is deep enough that almost any geometry target is achievable within the MacPherson architecture.

For the classic car crowd who own 1979-and-earlier Mustangs with the traditional front suspension, this isn't an issue. The point is that the Mustang family's suspension history is more varied than people outside the community realize.
