Opinions wanted for replacement Rear Spring selection. Thank you

Ice,

Why the torque warning? Always torque anything properly. Did you under or over do it? Did the u bolts break or fall off on you? What was the lesson that you learned?
I over-torqued cause i'm a moron and honestly never had used a torque wrench on ubolts and never noticed a problem, springs were like buggy springs and i couldn't budge the rear end, like 1" even.. torqued them properly and it settle bout 3" and moves like butter now. It does make me wonder how much better cars in the past i had could have felt/handled..
