Should you not want to do the math, I calculated the following. I use these calculations with optical systems I have made to align my vehicles. I suggest the use of a laser pointer (sufficiently mounted and referenced to level) to do determine level and parallel for the wheel pads Thank you for having the patience and taking the time to post Stretch

When you consider that 0.002 inches (roughly 0.5 mm) is one minute of angle, PAY ATTENTION TO STRETCHE's admonition about bearing adjustment and wheel straightness. It makes a huge difference
