The Overall Package
In addition to the advanced engine, the SVO featured several key modifications over the standard Mustang to help increase performance. The front suspension geometry was modified, 15:1 ratio power-assisted rack-and-pinion steering system replaced the standard system, a limited slip, 3.45:1, 7.5" Traction-Lok axle was added for the first year of production (later models used a 3.73:1 ratio, 7.5" axle), a new, ventilated four-wheel-disc braking system replaced the GT's disc/drum setup (a first for the Fox platform), specially designed pedals were used to aid "heel-and-toe" shifting and a complete Koni suspension system featuring specially tuned adjustable struts, shocks, and horizontal dampers replaced the setup used on the Mustang GT. Five-lug, 16 × 7 inch aluminum wheels wearing P225-50R16 VR Goodyear Eagle "Gatorback" tires were standard as well (originally shod with German Goodyear NCT tires, and later Gatorbacks). The rear disc brakes, the five lug hubs, the sixteen inch (406 mm) wheels, the quad-shock rear end (early 84 units used a solid steel traction bar with a rubber cover), and the Konis were used on the SVO before any other Mustang.
Interior was only available in charcoal grey (leather or velour) and features included adjustable sport seats with lumbar supports, a leather-wrapped tilt steering wheel, shift lever, and emergency brake handle, power windows, door locks and A/C and a premium stereo system, options that weren't normally found on small American coupes. However, an optional Competition Prep package deleted many of those features to save weight.
The exterior had a unique front grill and hood that was only used on the SVO line, thinner side moldings, smoother sail panels behind the rear quarter windows, small rear wheel spats and a biplane spoiler that was also unique to the SVO. The pinstriped taillights introduced on the SVO were later used on the Cobra "R" model as well.
