those tools mean nothing without the proper specs. problem is with our old cars that came with bias ply tires is thats the specs that the computers have in them. you get some guy that doesn't know anything but how to put the marks in the green area and you wind up with a bad alignment. you can have a guy with the old non computer tools give you an awesome alignment because he knows and under stands what he is doing. its more about the guy thats doing the job then is is the latest fancy all the bells and wistles machine.
