Rear shackle help

You stated its sitting high on one side. I'm assuming that's the side with the straight shackle? If so, that's why. I'm wondering why that one side is higher. Usually that happens with super stock springs. Maybe call Espo and ask them if that's normal with the springs you got. If there new installs maybe give them time to settle. Also did you torque all spring bolts and U-bolts with the weight of the car on the springs?
