Sterling Beauty - Kelly’s 2011 Ford Mustang GT

With a touch of red accents, AmericanMuscle customer Kelly’s Sterling Grey 2011 Ford Mustang GT demands attention. On the exterior, Kelly added a new upper grille, rear spoiler, panel splitters, painted calipers, drilled and slotted rotors, and new mirror covers. To further incorporate the hints of red, she painted parts of her engine bay to complement the theme. She installed Ford Performance lowering springs, a Corsa axle-back exhaust with resonator delete and Stainless Works X-pipe to improve her GT’s ride quality and sound. She also installed a set of 20-inch Rohana staggered wheels to tie the look together. Check out some of the standout mods below and see the full collection at

Finding Potential

To unleash the potential power of her GT, Kelly installed a SCT SF4/X4 power flash tuner. Right from the factory, manufacturers program vehicles to cater to the needs of the everyday driver, not the performance enthusiast. The computer settings on a stock Mustang are, therefore, calibrated for the original components. Upon adding some extra mods to her car, Kelly knew she needed to recalibrate the computer to achieve their full potential. After loading the tune onto her Mustang, Kelly’s car achieved noticeable gains in horsepower, torque, and fuel economy. At just a mere 2.7 inches wide and 5.5 inches tall, this flash tuner is also super easy to store right in the center console or glove box. The cord is detachable, and there is no need for any battery or power supply. It simply uses the power right from the car’s diagnostic port or USB. With this WiFi-capable tuner, Kelly can read and clear trouble codes instead of going to the dealer. The full color LCD display makes it easy to read, log, and monitor important sensor data like air/fuel ratio.


Stealthy Styling

To give her GT a whole new attitude that could be easily read from its “face,” Kelly went with a Roush High Flow Upper Grille. The grille adds sleek styling to the front, while also improving performance. It deletes those tell-tale factory fog lights from the front grille and replaces them with a 5-horizontal bar design. The result is a much cleaner look and increased air flow to the radiator, by approximately 40 percent, for improved engine cooling. The Roush grille is designed with the original OEM CAD data from Ford to ensure perfect fitment. It is crafted from injection molded ABS with a black, stipple textured finish for that aggressive appeal. It’s ultra-lightweight and highly durable for the best of both worlds in terms of construction. This grille is also as tough as it looks with resistance to heat and impact for added longevity.

Aerodynamic Rear

Moving along to the rear, Kelly decided to change up the appearance a bit with a SpeedForm GT500 Style Rear Spoiler. This spoiler is a highly popular option for S197 models, and for good reason. It adds a menacing appeal to the rear without being over-the-top. The modern touch complements the streamlined profile of her 2011 GT and adds a sleek, aerodynamic style for a race-inspired look. Manufactured from high-pressure injected molded ABS plastic, this spoiler is extremely durable yet very lightweight. It also came pre-painted to perfectly match Kelly’s Sterling Grey GT to make it look as though it was “born” with it. This spoiler covers the existing holes left in the trunk lid by the stock wing and does not block the view of the third brake light.

All-Around Flair

For true race-inspired styling, Kelly opted for a pair of Roush Side Rocker Panel Splitters painted in a bold red color. It fits in perfectly with her accented color scheme throughout the rest of the car. These rocker panels are the exact ones found on the special edition Roush Mustangs. They are made from OEM-quality, high-pressure injected, molded thermal plastic olefin (TPO) for a long-lasting and extremely durable construction. These panel splitters feature a grained texture for an OEM look that is also functional, in that is increases longevity against rock impacts from daily driving. Since they install right onto the bottom of the stock side rocker panels, installation was a breeze. This was a smart choice, especially since the panel splitters are a great way to tie together the bright red front lip to the accented rear diffuser. It also gives the effect of having a much lower profile to give it that aggressive stance when standing still.
