Test-Trak always conducts 4-wheel
alignments because monitoring of tyre wear is always part of any
on-road test. We have adopted the race car practice of using vehicle
mounted bars to create parallel string lines. We manufacture bars
that utilise number plate mounts.
There is a version where the
bars fold (like a pool cue) to make them easy to transport. Performing
a wheel alignment from first principals is more reliable than
electronic machines and can be performed easily in locations remote
from the workshop.
