To imbibe the 2006 2007 Ford Mustang Shelby GT-H with a genuine performance kick, the Shelby Team raided the Ford Racing Performance Parts (FRPP) bin to add additional adrenaline to the already-powerful Mustang GT. The car's 4.6L V-8 automatic powertrain comes with a special racing Power Pack that includes a 90mm cold air kit, a muffler kit and Ford’s racing engine calibration. To get the extra power to the ground, FRPP also added its Handling Pack, which brings special dampers, lowering springs, sway bars and a strut tower brace, along with a Ford Racing 3.55:1 ratio rear axle assembly. These modifications bring the GT-H’s horsepower to 325 and torque to 330 ft lbs, a 25 HP and 10 ft lb increase respectively.
