The team at ROUSH says the supercharger delivers greatly enhanced thermal efficiency, produces higher volumetric capacity, and enables higher supercharger operating speeds, all of which allow for more power and better fuel efficiency in a smaller, lighter package. In addition, the car’s PCM was calibrated by ROUSH engineers.
The Stage 3, which rides on 20-inch wheels (chrome or hyper black) and ROUSH/Cooper co-developed RS3 ultra high-performance tires, is equipped with a custom performance suspension system. We’re talking about a larger, stiffer front stabilizer bar to reduce body roll and provide balanced, neutral handling. The car also features a ROUSH designed anti-wheel hop kit, twin-tube shocks with unique valving, increased rate springs, as well as upgraded bushings and jounce bumpers. According to ROUSH Performance, its chassis engineers spent thousands of hours in development and testing to create the perfect set up to aid in acceleration, cornering, stopping and ride quality.
Beneath the hood, you’ll find a serialized Stage 3 plaque and a chassis build plaque.
Other exterior goodies include rocker panel and rear fascia side splitters, a newly designed ROUSH hood scoop, a three-piece rear decklid spoiler as well a new ROUSH rear aero valance featuring race-inspired diffusers and integrating new dual chambered, chrome exhaust tips.
And then there’s the graphics package. No ROUSH Mustang is complete without one of these. The 2013 Stage 3 graphics package is fully customizable, and available in multiple color combinations to allow owners to personalize to their taste, a ROUSH front windshield banner, a Stage 3 badge in the upper grille and ROUSH "R" fender badges. For that extra added touch, the rear decklid receives a Stage 3 badge, a faux gas cap "R" badge and is finished with Jack Roush's signature graphic.

In addition, drivers can wrap their hands around a suede wrapped performance steering wheel, while checking out the car’s vent gauge pod and LED boost gauge. The Stage 3 returns once again with a white or black shifter ball, and is equipped with billet aluminum racing pedals.
An optional light bar is available for convertibles, and ROUSH illuminated sill plates are available on Mustangs with the ambient lighting option.
