So if you switched from a 10” 375lb spring to a 8” 375lb spring and dropped the ride height by 1”, there would still have to be a 1” negative preload involved, and the spring would have a 1” gap between the spring and the spring seats when fully extended, same as the 10” spring and dropping the ride height 1”. The only difference between a 10” and 8” spring would be at the bottom where the adjuster nut would be at a 2” difference. The top of the spring/shock would be the same.
It seems like the only way to drop the ride height without having to use negative preload is to go with a spring with a lighter spring rate. And if you don’t want to do that, then negative preload seems to be the only answer.
A shorter spring you won’t need negative preload. You can crank up the perch to where it should be. I hope anyway. And in the range where it should be for good ride and handling, thought to be in the middle of the 40/60 % travel range the front is only 1”. Not to sure that matters, if it was so critical you couldn’t be at stock height or a lower drop. But it’s really Ridetechs responsibility to correct this. He can’t even get the height much less then stock the way it is now.

Hope he gets it fixed
