Thanks, Flar! That's exactly what I needed! Those numbers look pretty good. The front springs look like they're on the higher end, but nothing out of the ordinary. And to answer your question, it's perfectly reasonable to have a 10x stiffer rear spring, because of the mechanical linkage in the rear. I'll try and pull my shock soon so that I can get some detailed measurements. That should be the last thing I need to pick a new spring. I'll fill out a worksheet from Racetech with the dimensions and then post it up when I'm done.
