International journal of science, engineering and technology research (ijsetr) volume 5, issue 4, april 2016 coil spring rate depend upon various factors like coil wire material , coil wire thickness and length modification and fatigue stress analysis. Coil spring modification technical engineering essay a vehicles appearance can be improved by lowering the car height this can be achieved by heating or cutting the coil springs. The analysis results show that there only limited effectiveness on coil spring so the improvement plans were proposed to replace the coil spring with an air spring and setting transverse damper. A wave spring is made from coiled flat wire with waves added to give it a spring effect wave springs are superior to coil springs in certain applications because they provide lower work heights with the same force.
