bushings. Granted, if your suspension is adjustable, don't set it too soft in the rear (I think it was the compression). When I did it started to hop a little then I returned it to previous setting and the problem was gone. I barely know about suspension but reading on the Dodge Demon, I notice they went with softer springs with harder dampening. I guess the theory is the softer spring will allow more weight transfer to the rear and the harder dampening will push down on the tires preventing hopping or loss of traction. Then again it is my guess.
