Fastrax review and alignment questions for the pros.

And here’s one that’s very technical. Like hard to read technical. It actually works through deriving the equations for how the process for measuring castor works.

What all that math gobbledegook means though is that the turn angle doesn’t matter as long as it’s symmetric, but a wider turn angle spreads your measuring errors over a wider range, so, more accurate.

For general knowledge:
I got as far as this and hit a mental wall with theory.
Does this mean that on a complete alignment that castor and camber are set with zero toe and then I have to reset the toe to what the factory calls for. (1/8 inch toe in)?
I hope not.
And while we are on it, does toe even have to be set before the others?
