Maybe you are hyper sensitive to stuff. Or I drive slow.
10" is a lot of suspension travel for most scenarios. Though it did, I didn't notice the lateral displacement going away when I went from an angled panhard to a triangulated setup.
To be fair, the 'silver bullet' Was coilovers and air bumps on all fours. It could haul ass on some pretty messed up forest/fire road stuff and got air(I'm no Robby Gordon) on the little country road irrigation canal rises.
If my wife drove it and got some distance between the tires and pavement she would end up in the other lane when landing and getting that panhard shift sensation.
Panhard very much resembled the 80 factory setup (though both drive side frame attachment) Zin relationship to the axle/ground.
