Just curious as to what affect changing spring rates would do. For instance, say I'm using a 9.5"x3" shock, can I run a spring that is 400x3.25 or 400x3.0 or 400x2.75? I read that the second number is the travel of the spring, so would I want to use something that was at least x3 or higher for a 9.5"x3" shock? if I used the 400x2.75, would I not get the full stroke form the shock? Thanks!
