I was thinking about the getting a tool to do mine eventually, so I'm curios to see how you make out.
I was looking at the racing tool sites with similar alignment tools and it appears that these guys do this before every race.
So it make me think that if they can get a race car dialed in good enough to race with, I should be able to get mine bang on the mark.
There is no evidence of uneven tire wear after over 5 years of use.
The tire's wear indicators are not exposed or even close to it.
The car does pull to the left slightly and the effect is not enhanced
by hard braking. So why do an alignment? Well; have never done
one before, sounds like fun, car probably needs to checked at least,
have replaced several suspension components and I get to learn more
about how my car works.
The device is made to be portable and you are right, if it is good
enough for the race circuit......
