Vehicles used in a manner where they could bottom out the shocks (such as drag racing) should use a higher rate spring and a bump stop to help prevent shock damage. Multiply that answer by the current spring rate 500 lb/in 2. front and rear. We go a step further giving you the additional advantage of convenience and product longevity with the inclusion of all necessary heavy duty installation hardware. has been designing and manufacturing coil springs for the automotive racing industry. Some people compare spring rates and not wheel rates themselves. As is our "bounce test" - a very simple way of measuring spring frequency directly, without calculation with motion ratios. Rear coilover shocks have always been a good way to add a lot of adjustability and tuning to the rear of a drag car but few people understand the process to installing them and setting them up. Then at the top of the page there is a link for the spring rate calculator.
