That's a symptom of failed shock absorbers, not cut springs. If you push down on a corner of the car and it bounces up and down more than twice, the shocks are dead.
Cutting the springs will increase your spring rate (make the springs stiffer), which I've read will wear out your stock shocks alot faster (so the two are related, but not the same). When you increase the spring rate, the shocks go from relatively long, slow impacts to short, sharp ones. You could get stiffer aftermarket shocks to handle the changes, but why would you spend money on shocks and use cut springs?
You could try the ghetto method for decompressing your springs and then take out the cut part. I actually prefer it over using a spring compressor:
1. With your car sitting on all four wheels (so the spring is being compressed by the weight of the car), take off the nut (only do one spring at a time) that holds the shock absorber shaft to the top spring perch.
2. Lift that corner of the car up and the shock shaft should slide out of the perch as the spring decompresses.
3. Take out your cut section of spring, the shock or whatever it is you're doing that requires decompressing the spring. You might need to push down on the suspension to get the clearance you need, but don't get under the car unless you set it down on a jack stand first.
>A4. If you're replacing the spring with something that won't be compressed when simply bolted together with the shock, unbolt the upper spring perch from the car and bolt it back on the end of the shock shaft.
A5. Lower the car, making sure the spring perch slips back in where it's supposed to be. Bolt the perch back on the car.
>B4. If the spring needs to be recompressed, set everything back together and gradually lower the car, making sure the shock shaft slides into the upper perch/bushing. Keep in mind that you're compressing a spring before you decide to stick your fingers in there to guide the shaft.
B5. Put the top washer and nut back on the shock shaft.
