Which of these part over the Fox isn't the upgrade? The racey 4.6L DOHC 305hp 4V engine? The all wheel antilock disk brakes with 13" rotors up front? The revised
suspension geometry? The 5-lug wheel/tire upgrade? The stiffer, more rigid unibody and outer shell? The more ergonomic and functional interior?
It's funny....with the exception of the 4V engine swap, 95% of the Fox Mustang owners I know try to at the very least mimic all of the above upgrades that came standard on his Cobra?
You and I are normally on the same page my friend, but looks are subjective. From every other aspect, the OP's Cobra is indeed an upgrade over the Fox.
