How It Works
Spindle-based laser measurement — the only way to achieve true alignment accuracy
Why Traditional Alignment Fails
String Methods
Traditional string alignment measures from the tire surface, introducing inaccuracies from uneven tire wear, sidewall flex, and inconsistent tension.
Rim & Tire Runout
Shop alignment racks measure from the rim, but rims and tires have inherent runout (wobble). Even small deviations compound into major alignment errors.
Excessive Tire Wear
Poor alignment causes uneven tire wear, vehicle wandering, and darting — problems that factory alignments often fail to correct.
Spindle-Based Laser Measurement
True Laser Track attaches directly to the steel center spindle where the wheel bearing is located — the exact center of the rotating front wheel mass. This eliminates all inaccuracies from rim and tire runout.
Why the Spindle Matters
- Measures from the exact center of the rotating wheel mass
- Patented adapters machined with precision
- Eliminates rim and tire runout completely
- Military-grade laser for thousandths-of-an-inch precision

The 3-Step Process
Complete precision alignment in three simple steps
Attach to Spindle
Attach the patented True Laser Track adapter directly to the wheel bearing center spindle or hub. The adapter is machined with precision for absolute accuracy.
Interchangeable adapters available for NASCAR, Spyder, Ryker, Slingshot, and more.
Laser Measurement
Military-grade lasers project a precision beam that measures front toe, skew, and overall toe. Readings are accurate to thousandths of an inch — the width of a human hair.
Three measurements: front toe, skew, and overall toe for complete accuracy.
Perfect Alignment
Make adjustments based on the precise laser readings. Verify alignment with a final measurement. Your vehicle is now aligned to NASCAR-level precision.
Works on any near-level surface — no alignment rack needed.

The Old Way vs. The TLT Way
See why measuring from the spindle changes everything
The Old Way
Pull a string along the side of the car using jack stands. Measure in to the wheel, tire, or rim. The problem? "Run out" in rims and tire sidewalls makes this method fundamentally inaccurate.
The Cost of Inaccuracy
With the old method, toe set at about 1/8 inch = 153 inches of tire scrub per lap on a half-mile oval.
The TLT Way
Measures directly from the spindle. The spindle/hub end has virtually no run out — less than half a thousandth of an inch. This is the only true reference point for alignment.
The TLT Advantage
With TLT, toe set to 20 thousandths = less than 20 inches of scrub per lap. That's nearly 8x less tire scrub.
Before You Start
Complete this checklist before beginning your TLT alignment
-
1
Verify No Bent Parts
You cannot have any bent spindles or a bent rear end. The good news: TLT will find bent parts during the alignment process if they exist.
-
2
Set the Ride Height
Set your ride height using ride height blocks before beginning. Alignment measurements are only valid at the correct ride height.
-
3
Remove Covers & Clean Surfaces
Remove front dust covers and rear drive flanges. Clean all mounting surfaces to ensure the adapters seat properly.
-
4
Center the Steering
This step is essential for setting the right side wheels parallel. Make sure your steering is locked in the center position before measuring.
-
5
Bolt TLT to All Four Hubs
Attach the TLT mandrel/laser with your specific adapter to all four hubs. Each vehicle application uses a purpose-built adapter for a perfect fit.
What TLT Can Measure
One system, complete alignment capability
Advanced Techniques
Get even more out of your TLT system with these advanced methods
Check Contact Patch
Turn the front laser down and project the rear laser forward until it meets the front laser dot. Where the two beams intersect reveals your exact contact patch offset — critical data for chassis setup.
Check Roll Steer
Measure rear roll steer within thousandths of an inch. Real-world example: Two identical cars — one with 20 thousandths out turned well, while the tight car projected in 20 thousandths. That tiny difference equated to 2-3 tenths per lap.
Check for Bent Rear End
Establish baseline dimensions before racing. After an incident, bolt adapters to the RR and LR, project dots forward and back, and compare measurements to your baseline to quickly identify bent tubes.
