I will have to take the photos later tonight after work. It may have to do with the rear spring weights or my settings on my adjustable shocks and struts. They are BMR SP067 handling springs I believe. I do love the BMR springs. Prior to that I had Vogtland sport springs which dropped the car about the same amount 1.2" advertised but they were a larger diameter and rubbed the body at the spring tower. I don't remember the tires rubbing with them so possibly if the BMR springs did drop 1.5" that would be .3 inch difference.
Maybe they only rub when the body twists going over a curb at an angle?
