The standard GT350 package adds $33,995 to the base price of the Mustang GT. For that cash, you get a Shelby Ford Racing Whipple Supercharger, racing suspension
with a caster/camber plate, upgraded and duct-cooled brakes and Cragar 19-inch wheels wrapped in Goodyear tires.
The makeover also includes body modifications front, back and sides, Guardsman Blue vinyl stripes, a reworked interior and enough Shelby badges to make sure your Mustang’s pedigree is never mistaken.
This stuff would cost at least $20,000 to add plus time and trouble. So it is not as bad a deal as some suggest. Plus you have a limited edition and Shelby name so it is something that could be "collectible".
I would just add a Kenne Bell supercharger for power and upgrade the brakes, suspension and wheels and tires with my own mechanic. Which is what I am doing at a cost of $15,000 or so... The supercharger will be the last thing I add as it will make engine warranty claims much harder to make...
