Shaking at 60mph

I got an infrared thermometer and checked the temps of the rotors after driving for a bit.

What part of the rotors should I be checking? Any part of the rotor face?

Temps didn’t seem to vary by much. They were cooling down quickly I think. I will have to do another test quicker, but wanted to check on where I should be checking the temps.

I doubt the iron rotors are cooling too quickly. It might be hard to get a reading because they are so shiny. I would expect that your front temps will be higher than the rears but have never checked it to confirm.
