Hello to fellow Shelby owners............this is my first Shelby GT 500, 2007, and am loving it. Owned Mustang GT's and Mach 1 but my GT 500 tops them all. Bought my baby 3 months ago with only 22 miles on the odometer..........currently have 3500 miles booked and already done some mods........cold air intake, exhaust and tune...........looking to change rear to a 3.73 and suspension...................any suggestions are welcomed.
