If it takes 100 lbs. to compress a heavy spring 1 inch. And 100 lbs. to compress a light spring 10 inches. That would mean in one inch of rise the heavy spring will be at neutral. Where the light spring would still have lift pressure after reaching 1 inch for 9 more inches. That is why /6 bars are used for drag racing. A quicker reaction for lift.
