I forgot to load up pics of the dual rate set up. It's the 11 lb/in rate (helper spring) over the 240 main or 11/240. This is a zero pre load set up. I can control the block point of the helper spring as well as change the ride height via the pre load position. This way i can set the sag to about what ever 10 to 50%. The variation of this will be a triple rate set up using 11/350/240 11/350/215 spring sets.
These will come into play as I precede with the topic.
Now that we have an idea on spring rate, travel and loads on the spring it is time to move to the wheel and it rates compared to the springs and how those weird charts work when we enter toe calculate the spring rate. We discussed motion ratio or leverage ratio what ever you prefer. So now we can compare this to the arms motion ratio that the calculators use. For me they do more harm than good in way of confusion. anyway, I will try to break it down a little so it makes since. I will use an example of the pilot front and try to talk my way though it.
