[QUOTE="E-Ticket, post: 766967, member: 20985"] Hey SusanE, Yup. When ever you shorten springs (by cutting off some coils) -- so that you can put in spacers to reduce travel/ride height -- you stiffen the spring rate. What might be a .36 spring... when shortened becomes a .38 rate spring (stiffer). It has to do with the overall free-length of the springs, number of coils, pre-load pressure.... blah-blah. (This is where an expert steps in and really explains the why -- I simply know that this is the effect). For the ride height, proper pre-load range, and supple ride that we wanted for Susan (115 lbs., 5'2") -- our suspension guy is doing his experimentation/shortening with .36 fork springs and a 4.3 rear shock spring. These are *really* light springs for the 250x - but that's what it's probably going to take. And once you go to really light springs like that -- he'll also be adjusting the valving to match. Right now, with the Kouba lowering link (which stiffened the shock's rising rate [leverage] while it limited the ride height), we can't back out (soften) the rebound adjustment any more. Hence, the need for revalving. When it's *finally* done, it's going to be sweet. But you really need to have a knowledgeable expert when you start changing this many suspension parameters. Hope that gave you some food for thought! - RandyB [/QUOTE]
