Earlier this year, Shelby announced it would focus less on building complete cars and more on selling parts, and that transition began when the company brought much of its manufacturing in-house and created a new speed shop to customize Mustangs at its Las Vegas facility.
Looking to the future, Shelby has now posted a query online asking its customers what they want to see from the company, and in the process it's proposed four Mustang aftermarket packages ranging from a V6 model to a twin-turbo Shelby GT500.
While probably the least likely to appeal to the everyday Mustang enthusiast because of its cost ($100,000 not including the car), the twin-turbo GT500 obviously caught our attention. The concept, codenamed 2010-04a, would be based off the 2007-2009 GT500 and would feature a twin-turbo system with variable boost good for 1000+ horsepower at the rear wheels in addition to an adjustable suspension, widebody kit, 10-point roll cage and more.
On the other end of the spectrum, Shelby is considering offering a package for 2010+ V6 models carrying the Shelby GTS moniker. This seems more likely to make it to production, especially since Shelby has already produced a working prototype. The GTS would feature various visual and performance upgrades and the package would retail for somewhere between $9,000 to $12,000. Finally, the last two concepts are based on the new 2011 Mustang GT and would feature the same styling upgrades as the V6 version. Follow the jump for a full list of proposed features for both the twin-turbo GT500 and the GTS model, and let us know which packages you think Shelby should offer.
