I installed my rear only BOSS T springs and BMR adjustable panhard bar last week, and I noticed that the passenger side sits lower than the drivers side. I measured and it is 1/4 inch lower. I have only reversed the car out of my garage to take after pics, so I have about 30' of driving on them. The axle is almost dead on center. Any reason why? I made sure that the pigtails on the springs were pointed to the rear on both sides before tightening.
