Typically there are a number of coil spring options that will hold the car up at the desired shock C-C, depending on how much the spring is compressed. A heavy rate spring will require a little and not store a lot of energy. A light spring will need to be compressed substantially more and will have more stored energy that can be used to help get the rear out and the tire applied if needed. It - along with a good shock to control the housing - will give you another tuning tool. I've personally never tried it on anything.
