The 225 hp and 185 lb.-ft. increases come from the signature Roush supercharger. Stronger internals and lowered compression ratio (9.8 down to 8.6) help keep the engine in one piece.
Roush continues to amaze us with its Stage 3 version. Based on the 2010 Ford Mustang GT, the Stage 3 is loaded with improvements. Upgrades include a new exhaust, 14-inch front rotors with four-piston calipers, optional 20-inch rims and an array of body components including a new grille.
Interior enhancements include embroidered Jack Roush signature leather seats, illuminated sill plates, and an engraved badge with the car's serial number.
The Stage 3 will be offered in a limited supply of 103 examples with a price tag of $59,945.
The Roush 540RH is the sleeper model of the two. Sharing the same power numbers as the Stage 3, the 540RH will be less likely to get you pulled over for looks alone. The 540RH contains the same suspension and engine modifications as the Stage 3 at a somewhat more reasonable price of $46,145.
If you are interested, now would be a good time to visit your local Ford dealership. The cars will begin shipping in October.
