GMD used it to calculate my front spring rate. Since I came out at .981 I did a .975 split. I have a 1.0 on the right and a .950 on the left. I cant report as of yet how good it is because I havent been on the track yet.

I've used the calculator twice; on my GEN III and my GEN IV. Both times when I replaced the spring with the racetech bike had improved handling.

Right now my shock is being revalved and the spring is being tested so I will have more accurate info soon.

I know the bike handles better with the new spring thats for sure.

FWIW, their stock spring measurement has been known to have issues. From my experience its on the firm side, so biased toward track. Preference comes into this quite a bit and given that I tend to like the softest spring that is in range I factor my sag figures and real world feel before to gauge any 'recommendation'.

At the end of the day, they are in business to sell springs and parts, so take it with a grain of salt if you are not experience issues and your sags are close.

Got to agree with this. They and some of their dealers and others.. will upsell you to the moon if your daft enough to listen.. when in a lot of cases parts aren't needed. Buyer beware..

Race Tech sets their spring rates a bit on the stiff side. They do this because it's better to have too stiff of a spring than too soft. And without having the rider and the bike in front of them to measure sag it's better to error on the side of caution.

Stupidity and Motivation are a dangerous combination

I have to would have to disagree with this. Yes, SOME dealers are out there to make the $$$ and that's all that they care about. But there are a lot of dealers out there that do care about the rider and their experience.
