Cutting coils will stiffen the ride- - - -not soften it. Think about this- - - -if you stretch out the spring into a torsion bar, and twist it, a certain amount of torque will be needed to make it move. Now cut off a few inches and twist again. It's going to take more force to get the same amount of twist. Cutting coils off of a spring will lower the ride height- - - -but also stiffen it. If you want a softer ride, weaker springs are going to be needed.
