Lol you're almost there man...

Cutting a spring increases the spring rate, but decreases spring height. The loss in lift is a result of the loss in spring height which has a much larger effect than the lift from increased spring rate.

So basically all im doing is calculating the final spring height for a given load. Comparing the final equilibrium spring heights is an indication of how much ill lose/gain from my current setup. But somethings not adding up so I think the free heights ive calculated for the cut springs are wrong (ill verify when my new springs get here)

You can pretty much ignore all my numbers. Im really posting them all more for the sake of documentation so I can come back here and read what ive done.
