So then I did some looking at the front ends I have to chose from and it seems if I got with the Suzuki GSXR one, it came factory .790kg/mm, not far off. The Kawaski one I have came factory spring rate of .850kg/mm. Since these are the two for runners of what I have, how close of a match do some of you more experienced guys feel this would be or am I really off base with this comparison? These would be a little stiffer than Racetech recommendation but not by far I'm thinking. What concerns if any do we think I have using either of these like I'm planning?

You should be fine with either. If you already have the Kawi front end, then just use that, should be fine. Both much better than stock so you won't notice the difference in spring-rate too much between the two upgrades. I had calculated 0.8kg/mm from RaceTech's site and ended up having to add some extra preload anyway.
