I HAVE SEEN ONE BAR LET THE CAR GET TWISTED TOO FAR---GO WITH THE DUAL SETUP AND ATLEAST YOU SHOULD STAY STAIGHTER--ONLY REMEMBER THAT IF YOU DEPEND ON THE BARS AND SOMETHING GIVES OUT ON THEM -YOU ARE IN FOR ONE SCARY RIDE---I WILL MOUNT MINE ON THE MY REAR BUMPER OF MY RANCHERO!!--IF I GET THAT HIGH UP I WILL JUST HANG ON FOR THE SCARIEST RIDE OF MY LIFE :lol: :lol: :lol: :lol: --LIVELY IN ILLINOIS
