Spring-under conversion for no-lift crossover steer?

Suppose I wanted to convert my 81 to crossover steering, but didn't want to raise the ride height from stock. I understand that the major issue is having the pitman arm and upper tierod clear both springs, which is why it's invariably done with a front lift. What if instead I came up with two 4" lift springs, but mounted them under the axle (about 3" thick, plus 1" or so for the spring thickness) to cancel out the lift? That way, I keep my center of gravity low but still gain the normally required clearance for high-steer. Bumpstops would have to be lengthened because the next point of impact is the oilpan, and there'd be a shim game to play for proper driveline and caster angles, but it's still a lot less work than links and coil springs. Has anyone done this? Thoughts?

Haven't heard of going spring under on a mini. Most don't recommend shims for front.

Offroading lift springs are longer than stock to give flex. So requires moving spring hangars. Could look at removing a spring out of pack to lower lift and wheel spacers to give wider footprint in front and IFS rear axle or wheel spacers for rear.

Have heard the lifts like skyjacker that have stock length but more height are rough. I ran Downey rear lift springs they had no flex compared to longer Allpro's I'm running now.

That's another thing about spring under axle - it requires longer springs with more arch, and presumably flex better?

IDK, seen alot of LC and sami guys go to spring over. But longer springs do give better flex. Would be interesting to see.
