text: Ford also improved upon the handling characteristics of the GT500. The overall stance of the car has been lowered by 11 millimeters in front and 8 millimeters at the rear. The car also features Ford's new Electric Power Assist Steering (EPAS) that improves torque build-up and road feel which delivers quicker and more precise steering, increased effort on the racetrack or winding roads, and reduced effort in low-speed parking maneuvers. The car also has Ford's AdvanceTrac stability control system, which features a sport mode when pressed twice consecutively while stopped with the brakes applied.
  External improvements include an optional SVT Performance Package, which includes Goodyear EagleF1 SuperCar G: 2 tires, all-new lightweight 19-inch forged-aluminum wheels in front and 20-inch forged-aluminum wheels at the rear, a 3.73 rear axle ratio, and performance tuned front and rear shocks along with stiffer springs. The package includes a unique rear spoiler Gurney Flap for improved handling, slightly revised front and rear fascias, a new pedal box for improved clutch use, slotted brake dust shields for improved brake cooling, standard HID (high-intensity discharge) headlamps, MyKey programmable vehicle key, integrated spotter mirrors, and fold-down rear headrests. Optional is a glass top roof, previously available, starting in 2009, with the Mustang GT.
