Embarrassing isn’t it? The sporty Mustang’s underpinnings are anything but sporty. Watch this thing roll in the slalom with absolutely no finesse whatsoever. As we round this segment in a ’67 Mustang fastback with bone stock suspension and steering, the body wants to keep going while leaving a lame undercarriage behind. Despite a potentially great contact patch, these skins don’t stand a chance at adhesion because this Mustang suffers from a high roll center and virtually no sway control. CPP’s Mini Subframe Kit with adjustable coilovers, beefy antisway bar, and better geometry will change all of that.
