ROUSH Performance is back at it, delivering three new 2013 Mustang customizations, Stage 1, Stage 2, and Stage 3. Stage 1 is mainly aesthetic, wearing a sixth-generation Roush “R6” aerobody package. The Stage 2 model is a handling package, complete with twin-tube shocks, a stiffer front anti-roll bar, optimized suspension bushings, and Cooper RS3 ultra-high-performance summer tires. Stage 3 gives the classic American muscle car a 5.0-liter V8 engine with 565 horsepower and 505 lb-feet of torque. Expect the models in the backside of this month.
