The Laser is the new system that seems to work on three wheel vehicles, we used to cook on wood burning stoves and have an ice box that required ice to cool it. Times change and Laser Man is on top of this game. He is also very well known in the NASCAR world not only setting up the cars, but giving driving instruction to some top names, He comes from the racing world specializing in handling. He is very passionate in making sure any vehicle can handle the best it can. Its not that old school cant do it, but lasers are easy to use and so accurate. Look at all the construction that is done with laser leveling now compared to old school stringline. The same response was met from the spyder world and CanAm, but check with CanAm now, they asked him what he did to his after they rode it, his reply was he fixed it.
