[QUOTE="am_izham, post: 2086530, member: 5892"] u see, a coil spring is just a torsion bar (do a search on wikipedia) that is wounded up to form a coil. the nature of torsion bars is that the longer the the softer it will be and vice versa. so the idea of a cut spring is the same as cutting the torsion bar. yes, you still have the same spring diameter, same diameter of the wire, but it will have a shorter overall length of the wire as in shorter torsion bars thus, harder spring rates. but, cutting a spring by just a coil doesn't increase the rate that much depending on the design of the original spring. let's make some examples: a spring that has an overall height of 10 inches and has 10 full coils, if we cut one(1) coil we will increase the rate by 10% and at the same time reduce the height by 1 inch.
