Hey Bill,you are also right that they raised the fronts up for weight transfer.In order to get a wider tire under the back, they had to raise the back high enough to clear the tires.Unfortunately,then there was no weight on the back and the tires simply spun.Like you say, then up would go the front in order to put the weight back where it belonged, the back.So when you see a straight axle car, you just knew it was hot.Now they just tub them and unless you see them from the back, it's just another car. I have always been impressed by the axle cars and never really by the lowered ones.
