Other thing was total toe was spec'd to 3/16". The machine at dealer only did angle for the rear toe. I found an online calculator that converts the linear dimension if you have rear tire diameter.

I input 0.1875 for total toe and 25.0 for rear tire (255/35R18 PSS). That's the Michelin spec. Out popped 0.429 deg total or 0.215 deg per side. Pretty neat.

We had to convert the decimal angles to minutes. 12.9 minute per side and 25.8 minutes total. Tech was happy and understood. I did some simple trig and verified the website too. Look at the picture on the site and then it all makes sense. I have a picture of all of the parts I changed out. I will add it in a bit later as I can't do this from phone.
Fantastic.. let us know if you are ready to get together one weekend. I was thinking maybe July 22th or 29th?
