Is there any difference between the different stock wheels? The Deluxe package and Premium come with different style wheels, but I think they are both 17". Are the Premium ones lighter or something?
The Deluxe GT come standard with the 17in ponys that were new in '99. You can opt for the Bullitt wheels or chrome five stars similar to the '99 Cobra's. They probably all weigh about the same. If light weight is what you are looking for, check out the Steeda Ultralites, 17 and 18in.
