computerized alignment rack. The only one I can use now since my car is lowered is the alignment rack for skylines at a Nissan in town but not every Nissan has one of those. As for an old school non computerized job, I've had one of those a while back and couldn't tell a difference, but that guy had been doing it for a very long time. Also I don't track the car or anything so I couldn't tell you details between the two.
