How to Use Gyraline

  • CALIBRATE

    Position the Gyraliner against a flat surface of the wheel, then tap the matching wheel on the screen to start your measurement.

  • MEASURE

    Switch to the other side of the axle and take your second measurement, keeping the top of the Gyraliner facing forward in line with the vehicle.

  • FINAL MEASUREMENT

    Return to the side where you took your first measurement, measure again, and you’ve got your first alignment reading!

How-To Video

Accuracy

Tested against professional-grade alignment equipment, Gyraline DIY achieves total toe accuracy of ±0.020°—surpassing the industry’s ±0.050° benchmark. With front and rear toe measurements nearly identical to a calibrated stationary alignment machine, you’ll get pro-level results you can trust.

  • Toe Accuracy that Mirrors Pros

    Gyraline’s front and rear total toe averages (0.35°/0.36°) nearly matched those of a calibrated stationary alignment machine (0.36°/0.35°), demonstrating virtually indistinguishable performance.

  • Camber Comparisons

    Camber readings also showed strong correlation—both tools measured within a 0.25° range, well within factory-alignment specs (±1.00°) and sufficient for precise alignment work.

  • Repeatable Results, Every Time

    Both Gyraline and the stationary machine exhibited high repeatability, putting Gyraline firmly in line with industry-grade tools. Given that Gyraline matches traditional gear within critical tolerances and stays within manufacturer alignment specs, it’s proven trustworthy for accurate, at-home alignment validation.
