Trackace Wheel
Alignment
I have found this device
which does laser wheel alignment, toe in/out only. As this is
usually what ends up being adjusted I thought it might be worth a
shot, the theory behind it seems very strong. Its very portable so
could be used at track days.
Plus I had the whole front
suspension out of the Nagari Sports and rebuilt it so was setting up
again from scratch.
So I spent my $145, as a
normal alignment is $45-$75 and takes 3 hrs by the time you wait at
the place! Then tried it on 4 vehicles, 1 had been aligned in the
last few 1,000 kms so I was expecting it not to have moved or worn.
Mazda 6, done 2,500kms
since last aligned was within 1’ or 0.1mm from the last setting,
which equals perfect.
Ford Ranger 4X4 ute, done
11,000km since last aligned, was within 5’ or 0.7mm from the last
setting.
So assuming the last
settings were as per the work sheet it all seems to make sense and
the product works very well. It’s very quick to use, about 3
minutes, which is good as you have to redo it each time you make a
adjustment. It also recalibrates ever time its used so each
measurement is perfect.
NSX which has done about
16,000km since last aligned was within Front 1.4mm and Back 0.7mm
from the last setting. They say it works on 100mm ground clearance,
which my standard 1995 NSX is to under the front lip, but I think you
can make it work lower than that. They don’t say it will do rear
alignment as its not checking with the front for reference (see web
page) but it still gives a perfect aft toe reading.
I tried to “trick” the
unit by making it read incorrectly but if you follow the
instructions, it seems to be nearly idiot proof!
Video of it. It is
actually better in real life.
Anyway I found it very
useful and quicker than hanging around alignment shops reading old
car mags! Plus I know it’s done properly…..

Just checked your blog >Sounds like a great unit. When I was rallying we used a similar set up but it required a tape measure. Fine for mid rally adjustments. I now have a uni lux laser alligner I purchased years ago and it will be getting a good workout on the Nagari when I get home. The damage from by Easter mishap does not seem to be all that bad just the steeering box and a bent box mounting. It will get a thorough check though. Baz
