Spring rates are only part of the story. It's the job of the damper to control that spring. Setup to work together, with the right R&D and internal construction they can produce good ride and drive qualities. So, spring rate isn't the whole story. Though I do understand the concern when less expensive systems trade control elements to deliver preceived ride quality.

Based on what we know about Zeal, they know how to dial in their damping. And knowing their product line, it a comment based on looking at specs for a Zeal coilover system that someone custom ordered,.....with rather high custom spring rates. In any event, better valving, allow's you to run higher spring rates without giving the impression your on high rates. And you can bet Zeal does not undercontrol the spring as a method to deliver that.

Wheel rate = how much spring rate actually makes it to the wheel to perform work. Notice how 100% reaches the wheel in the rear on the true coilover setups listed below.
