The car on turn in when it starts to rotate the rear end feels loose-disconnected for a split second, almost like it rises up a foot or two(thats an exaggeration, it does feel weird) then it finishes loading and bites down. That split second will scare the crap out of you. Will lowering the panhard rod fix this? Its very un nerving. What rear bump stops? What tires? Tires same model front vs rear? What pressure?
