The restoring force of a spring is the spring constant 'K' multiplied by the distance the spring is compressed, 'X'. So Restoring Force = K*X. When you shorten a spring by cutting out coils the spring can 'bottom out' on your suspension stops in 'bump' giving a sudden change in suspension geometry. Hitting a pothole while turning a corner at speed with shortened springs can easily cause a rollover, making the driver of that vehicle a candidate for a Darwin award. A reputable manufacturer of a drop spring will increase the spring constant so that the same restoring force is obtained with a shorter compressive length before hitting the bump stops. A drop spring made by a fly by night is just as dangerous as a spring you have cut yourself.
