The cars were offered in Three Stages. Stage l was strictly an appearance package, consisting of body add ons. Stage ll added a race proven suspension package, which pushed Mustang skidpad numbers into areas most pony car enthusiasts had never seen before. Pieces included Hyperco coil springs, Roush/Koni double adjustable struts and shocks,30mm front and 27mm rear sway bars. Stage lll included hot rod techniques and parts from the Ford Racing bin to bump up power from the stock GT by almost 50 horsepower. Roush Performance Products Not one to sit still, Jack created ROUSH Performance Products in 1995 to produce and sell aftermarket performance parts, including performance crate engines. Some of these high performance parts included iron and aluminum CNC ported GT40 heads for both 5.0 and 5.8 liter engines. Aluminum heads get larger Manley 1.94 intakes as well as Roush CNC ported Trick Flow heads for big blocks. Suspension bits included panhard bars for sn95 mustang, traction bars,and handling packages. What made these packages unique, was the level of engineering that went into making the packages fit together into one well thought out and sorted out car. One of the unique things you'll see in the early cars, is the unique ram's horn looking air boxes atop the engines, fed through the 3 piece fiberglass hood assembly.
