I see a benefit of having a "stiffer" pedal while off road. While bumping and jarring around as jeeps do, the extra pedal tension would prevent accidental heavy acceleration. In other words, a lighter pedal, with increased throttle response is more sensitive to the small movements.

Now that you mention it, I notice the pedal's requirement for some force. That being said its not an issue for me (maybe my big feet help). I'll be interested to see how this work for you in the real world. '

Also..not sure the spring rate..the more open factory smaller spring could be stiffer than the smaller, more tightly coiled spring. I"m sure a simple device could be used to measure the force to compress both to compare. Too many variables for me to wrap my mind around. Seems like trial/error would be the best way.

I'll wait for pickles results then copy cat!
