Yo Tundra!
I'll take a pass on being smarter than anybody...
How-some-ever, I did go through some of the same contortions you find yourself in when I was "designing" (I'm over-stating my ability, again!) the suspension for the Slotus. Speedway has a similar chart for "angle correction" that you can run your numbers through. That angle off vertical of the shock/spring is the culprit. I think it comes out to 556 lb/in, but maybe I didn't use the right MR correction.

As for the actual numbers, I think I have 350 or maybe 450 lb/in springs on the front of my car and about the same in the back. I'll try to remember to verify that later today when I'm out in the shop doin' stuff. Admittedly, mine is "track only" and I'm not concerned with comfort exactly... But, when you tilt the springs over, you gotta compensate...
Hope this helps! Good luck...
