We have the first details on the Roush kits being made available for the 2011 Ford Mustang.

Roush has released full details on their packages for the 2011 Mustang.  The American tuning firm will begin production on two different versions of the Roush Mustang as soon as Ford's own production commences.

The company's engineers have not yet completed work on performance enhancements for the vehicle.  These modifications will include re-tuning the 5.0-liter V8 engine that already produces 412 horsepower and up to 390 ft-lb of torque.  The company also plans to make their custom supercharger available.  It is unclear if any changes will be made to the six-speed manual transmission.

Unfortunately, the performance upgrades will not be available before the summer.  "We have a history of increasing the horsepower on each model year 427R Mustang, and that should continue with the 2011 as well," said company chief Jack Roush in a press release.

"However, exactly what the horsepower and torque numbers will be is too early to tell at this point as the engineering teams are still working through a myriad of details on the new five-liter engine."

What will be available are the "Roush Stage 1" and the "Roush Stage 2" packages.  The first kit includes a set of body upgrades, likely including a new front fascia with splitter, side sills, and rear wing.  The rear fascia will likely be touched up as well.  New wheels should also be available, including 18- or 20-inch varieties.

Stepping up to the Stage 2 adds both suspension and handling modifications, along with the body changes from Stage 1.

Pricing for the 2011 Roush Mustang kits has not yet been announced.
