Yes. It's a 3.1 ish. The OS was a 3.3. Not sure why Rob hasn't been more vocal about the results but I'm sure he has his reasons. Let's just say the owner is happy with the KN20. Hopefully ZCG will publicly post some numbers soon as they are impressive.

Was thinking my first set from GC in '95 or so had 5" adjusters. Just to clarify. Looks to me like you might run the spring to the bottom of the adjuster without getting the ride height you want. You could grind the perch off of the strut tube, but that's a hassle. The other solution is to run a shorter spring. Shortest spring that doesn't coil bind is always the best choice because it's lighter and it will resist bending sideways when it compresses. I started off with 10's, worked down to 8's and now run 7's, but I also have super stiff springs and run very low, so don't need 6" of travel.
