Roush this week launched its Stage 3 Mustang, packing 415 horsepower with 385 lb-ft of torque. “This is the best Mustang we have ever built,” said Jack Roush of the new vehicle. The Stage 3, 4.6L, 3-valve V8 powertrain system includes the intercooled Roushcharger system with custom Roush-calibrated ECM and several other performance modifications. This upgrade is a vast improvement over the factory stock engine which is rated at 300 horsepower and 320 lb-ft of torque. But this car is more than just being quick on the throttle as the more than 1G rating on the skidpad attests. The suspension upgrades include specially-engineered and tuned front struts, rear shocks, front and rear springs, front and rear sway bars and jounce bumpers. The front brakes are also upgraded with 14-inch front two-piece rotors and four-piston calipers.

Exterior styling is enhanced through the addition of a seven-piece body kit constructed from OEM-type materials which sees a front fascia, front chin spoiler, hood scoop, rocker panels, rear fascia valance and rear wing installed by Roush factory technicians.

Other amenities include lower valence fog lamps, custom 18-inch forged rims with high-performance tires, sport leather seat covers, embroidered floor mats, billet aluminum pedals including a new dead pedal, and the Stage 3 electro-luminescent white face gauge cluster. The car also has Roush badging throughout and a serialized engine bay plaque indicating the car was hand-built in the Livonia, Mich., facility.

Optional components to further customize the car include racing stripes, interior dash trim kits, locking lug nuts, trunk tool kit, short throw shifter, billet aluminum shift knob, and more.

The whole kit costs $20,225 and is available for both coupe and convertible versions. As with all Roush cars, the industry-leading 3 year/36,000 mile warranty remains intact and covers all components. The cars can be bought complete at some for dealers, or the kit can be ordered online.
