The numbers in themselves have a lot attached to it. The first being the maximum stroke length in relation to the total capacity. This is what needs to be matched first before anything else. In most cases these different rated springs don't share the same length or the dampers don't share the same extension length. The HKS is not that extreme when you consider its free length is short compared to some other springs and the fact it uses a secondary spring to take up the remainder of droop. I think a properly matched tender spring would make the droop sensation feel even better, but this could add another 300+ dollars in cost. In most cases that can be the difference of someone going with a different brand.
