You guys are correct about the size of the wheel and the size of the tire having an effect on the measurement from the ground to the highest point on the fender lip. I was really interested in the difference in the height of the front and rear. If we want to be precise and compare the static height of our cars then we should measure the distance from the CENTER of the wheel to the center point of the fender lip. I am curious how our cars compare to each other, and if the GT option changed this measurement (as it does on the 65 66 cars) or if the distance remains the same regardless of the suspension option. Difficult to take this measurement since the center of the wheel is not always easy to determine.
