Yeah, but it's really all fluff at this time - "The 2013 Shelby Focus ST post-title package begins at $14,995 not including the Ford Focus ST and will be limited to 500 per model year."
"New Ford Racing suspension pieces lower the car while the wheels and tires improve grip and traction. The bigger Shelby spec brakes with drilled rotors enhance the stopping power; along with the sound of the Shelby/Borla exhaust makes it uniquely Shelby. Inside, the car has a complete Shelby branded custom interior, Shelby shifter and finished off with the unique Shelby CSM badge. On the outside, the Shelby is easily identified by its functional hood vents, hydro-carbon front and rear grille inserts, Shelby lettering and rear Hydro-carbon spoiler. Three visual graphics packages are offered, ranging from "traditional" Shelby stripes to more edgy Shelby checkered flag splash or competition graphics. Under the hood, Shelby American adds stylish hydro-carbon components and is developing an optional performance tune expected to significantly increase horsepower."
So no power increases included in packages that cost almost as much as the base car itself. Also, this is still a FWD car that will be prone to insane amounts of torque steer. Anywhere close to 300 or 350whp will probably mean an ugly end for any novice that decides to buy one.
