I run the old spring loaded bars for one reason. To keep from damaging the pan, headers, and diaper. They are set low and touch on every pass. they don't seem to unload the rear tires either. As you can see from this pic their touching even with the front end low. It does come up about a 12"-16". My car runs very similar to yours. 1.32/9.25/146.6
