Roush Performance is synonymous with high-performance Ford Mustangs, and for 2013 Mustangs, Roush will offer three stages of enhancement. For those who prefer cosmetics over performance, the Stage One kit consists of the R6 aerobody package, which includes a remodeled front end, a hood scoop, rocker panels, a three-piece rear decklid spoiler, race-inspired (not CFD tested) diffusers and new chrome exhaust tips. Stage Two is a step up for performance-minded Mustang fans. This package adds upgraded suspension components to the Stage One offerings. Improvements also include beefed-up stabilizer bars, twin-tube shocks, improved bushings and rear control arms to help eliminate wheel hop during generous throttle applications. Stage Two also includes 18-inch aluminum wheels with Cooper RS3 ultra-high-performance summer tires. For those willing to put their money where their mouths are, the Stage Three package is available with a supercharged 5.0-liter Coyote engine that churns out 565 hp and 505 lb-ft of torque. It\'s the highest horsepower street-legal Roush Mustang to date. The customization options continue in the interior, with a custom gauge cluster, special floor mats and a few other features. Prices range from $4,500 for the Stage One package to $16,500 for the Stage Three treatment, plus any additional accessories or add-ons ordered. Of course, these prices are in addition to the cost of a 2013 Mustang. Roush opened ordering to Ford dealers in March, and more than 200 orders have been placed. Check with your local Ford dealer for more information; Roush Mustangs will be on the lots this month.
