SmartStrings - Kit

SmartStrings allow you to simultaneously align and “square” the car, that is, insuring that the rear axle is running true and parallel to the front axle. Also, since our strings attach to the car, they move with the car so when adjustments are made, the vehicle can be rolled to settle the suspension without the bother of the gauge having to be recalibrated. Since you can adjust all four wheels relative to one another, you can set the car up however you like, or however track conditions require. Properly installed, the strings form a perfect parallelogram around the car’s own centerline! Combined with the SmartCamber you can now perform a full four-wheel alignment precisely and quickly; at home, shop, or race track.

  • Fast and simple to use. If you can read a ruler, you can align your car

  • Universal, three-plane telescoping design easily attaches to nearly any car or truck

  • Fits track widths ranging from 48”-85”. ( We do offer an extension bar that increases this range to 99”)

  • Quickly and accurately measures toe angles on all 4 corners at once.

  • Ensures both axles' wheels are aligned to one another (so the car does not crab)

  • SmartStrings stay attached to the vehicle so rolling the vehicle after making toe changes does not change its calibration

  • Ruggedly built for everyday use at home, shop, or race track

  • Durable carrying case for transporting and storage (available separately)

  • Widely used by Pro-Level Teams and enthusiasts, repair shops, educational institutions throughout the world

  • Our intention is you are keeping this tool for a lifetime, so we offer every part ala cart also. A Smart Racing Tool will never be antiquated.

  • Designed in California and made in Michigan USA.


From the Founder, Craig Watkins

"I designed SmartStrings about 26 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 dealerships using them to confirm calibration of their high-dollar alignment racks, to track days such as Hooked on Driving and professional teams around the world. And yes, when I was the chief engineer at Flying Lizard all those years we used both gauges - they still do."
