Judging by the number of Ford Mustang customizers at the 2006 SEMA Show, aftermarket builders are all the “Rage” with ‘Stangs. The Rage is also available through Ford dealers and the kit is made for 2005 thru 2007 Mustangs. The cars can also be purchased direct from the factory and are powered by either an optional 400- or 600-horsepower supercharged and inter-cooled engine.
