ROUSH Performance takes the Ford Mustang GT styling to a whole new level with the 2014 ROUSH® Stage 1 Mustang. Packaging all American styling and a full range of signature ROUSH-only options, the Stage 1 is sure to turn heads.
Exterior identifiers for the Stage 1, or RS1 for short, include a ROUSH front windshield banner, Stage 1 upper grille badge, ROUSH "R" fender badges, Stage 1 decklid badge, rear faux gas cap "R" badge and finishes off with a Jack Roush signature graphic on the rear decklid.
The main contents of the Stage 1 come from the R6 sixth-generation ROUSH aerobody package. This changes the front look of the car with the ROUSH designed upper grille, high-flow lower opening (grille eliminator), corner fascia aero pockets with driving lamps and front chin splitter. At the rear of the car sits the ROUSH three-piece rear decklid spoiler giving the car a sleek look without obstructing the view out the rear window. Moving towards the back are the ROUSH rocker panel and rear fascia side splitters to give the car an aggressive, low stance. Rounding out the tail end is the new ROUSH rear aero valance featuring race-inspired diffusers made to seamlessly fit the ROUSH’s dual chambered, chrome exhaust tips.
Interior styling touches on the Stage 1 include ROUSH embroidered floor mats, ROUSH center console button, Stage 1 dash medallion, Jack Roush signature graphic on the dash and under the hood is a serialized Stage 1 plaque.
A broad selection of optional equipment is also available for the Stage 1 including exterior, interior, suspension, braking and under hood components.
