Tesla M3P Spacers - marking question

[Scosta17]

Hi all. So my car has had this weird vibration for weeks. Did balancing. Alignment. Took it to Tesla. Nothing fixed it. Thought maybe the spacers were doing it but took those off and it persists. However when I took the spacers off I noticed a few odd things.

#1 on the front one spacer has scratches the other doesn’t
#2 on the back one has a blue pattern maybe from heat the other doesn’t.

These are the left and right of the front wheels. Note that the one with the heat marks doesn’t have scratches and vice versa so it’s not one with all the markings. Was curious if anyone had seen this or had any thoughts/ideas.

I am considering the same spacers for my M3P. have you figured out the vibration? What about the blue and marks. It's hard to see in the pictures but are the stud holes wallered out?

Blueing should not be a thing at all and if they are getting that hot then something in the brake system is having an issue and could explain the vibration.
