Of course you could always have the springs reset & do it properly. While they are out you could replace the suspension bushes with urethane ones, & check the shocks to see if they are up to the task.
The springs should come back with new interleaf slider pads, & when it's all together you will enjoy a new level of ride quality & handling.
I have done all this in my coupe, except for the springs, which will get reversed eyes next & the ride quality is great [for a 1200] while handling is noticeably improved.
