I wonder about this. Only driving my expi for a few short months, I've come to notice it's just sprung WAY to tightly. Assuming it's inherited the F150s suspension, which would explain why inside rear lifts off ground during slow speed tight turns. True, a sway bar may keep both rears on the ground. But not only are springs too stiff, it's basically an unbalanced vehicle with a front loaded distribution anyway like most cars.
I was always hoping the magnetic suspension would catch a lot of this over extension but so much for that. So if the ccs doesn't have the authority, and it was missed/ignored in engineering, I'm basically screwed with this driving flaw. Wouldn't it be easier to correct (via magnetics) a heavy load vs an oversprung normal light load?
I could always add about 700lbs of dead weight in the rear
