I designed SmartStrings about 21 years ago, to perform precise alignments in my garage at home. It became too troublesome to make a change to my car at home, then take it to the alignment shop in the morning, work all day then bust my ass to get back there before they closed and so on - too much stress. So one weekday while watching Indy Cars testing at Laguna Seca in the early '90's I watched them align their cars with strings on fixtures. It popped into my head I needed to do the same at home - so I did. People saw them and wanted a set and so I redesigned them so they were completely universal, usable on virtually any car, anywhere. The resulting design was pretty effective, and over the years SmartStrings has developed a broad following; from home use, to dealerships using them to confirm calibration of their high-dollar alignment racks, to track days such as Hooked on Driving, to professional racing. And yes, when I was the chief engineer at Flying Lizard all those years we used both gauges - they still do.
A new carrying case is now available and may be added in the options menu.
Note: It has come to our attention that there are some SmartString kits whose right and left yellow unions are too tight and do not allow the 3/4" telescoping tubing to move freely. We have fixed the problem and we are very sorry for any trouble and aggravation this has caused you. If you are having a related problem, please return them for a replacement set.
