Wonder if any of you or anybody else can answer this question. If you cut a coil off a conventional spring does it raise the spring rate?

I have been told yes from one and no from another.

You might give Cannon Racecraft a call. They manufacture custom springs for numerous applications.

I don't think the rate changes as it is more wire diameter and other build spec dimensions.

With bikes the critical measurements when determening spring rates are static sag (amount vehicle sags under it's own weight) and ride sag (amount of sag with rider and vehicle) the primary objective is to keep the shock valving in the sweet spot of the stroke over the majority of the course. Off-road bikes they have three stages of compression valving, if the spring allows the shock to ride too low into the mid-stroke the suspension get harsh and corner grip is impacted. I'm not sure how progressive valving is in vehicles though.

I do know that Cannon RC can build springs to your spec and needs.
