You can start by adjusting them to a lower setting and see what happens. If it's still sitting too high when they are adjusted to the lowest setting, they need to come off. If it's still sitting too high, re-index your torsion rods . . . and go back with stock shocks. Stock shocks do not have a spring around them and do not affect the ride height of the car.
It's best to adjust them with the correct spanner, but if you don't have it . . . maybe a pipe wrench?
