Yes; I forgone that thought on the KWCS after purchasing; the twin tube is definitely not track oriented and definitely leaves it far behind when talking about upper echelon suspension groups.

As for spring rate, would you happen to know what the range is? 570/800 to jump to a more track rate like 700/1000 I'd only assume you'd have to revalve and adjust.
I find the built in helper is a great idea. Yes, it complicates changing springs but lets be honest, 90% of kits never get their springs changed.

A single spring with a built in helper eliminates the helper spring and the helper spring perch, so two pieces which disappear vs a standard kit. This is great. The less pieces you have the better. KISS mentality FTW
