Read full description

SpringRithm is for anyone who has a coilover suspension. With a purchase subscription, SpringRithm allows users to be able to set up their coilover suspensions to their desired loads at their desired ride heights. SpringRithm can assist users who do not have access to a coilover testing machine/Spring Smasher to get their coilovers correctly tuned to get the right loads. SpringRithm not only outputs the dynamic loads that the springs will see in travel, but also tells the user how to preload the coilover nut in order to achieve the set load/loads. For users who do have a coilover testing machine/Spring Smasher, SpringRithm will save tons of time by instantaneously allowing for spring rate and load changes in order to find new setups and figure out how their dynamic loads are changed. SpringRithm also has a built-in database of springs in order to determine if stack setups will coil bind so that users will know if their setup is even theoretically possible. Why guess on what height springs are needed for a setup when you can know!
