I believe “Fe” is the element chart defined as Lead.

Thanks for the link. I would have sworn the front and back calipers were the same. The car is relatively new, but I've washed it twice and didn't notice.

You are not going to have a car with the same calipers in the front and the rear.

The fronts are 6 piston fixed calipers, and the rear are single piston sliding calipers. Your car without the "S" cap over the rear caliper is correct.

And I sit here with my palm planted heavily on my forehead! Back to “earth science” class for me.

Thank you

Wheel weights? Looks like you might need to have your wheels rebalanced

Also, those aren’t Audi factory wheel weights that you found. So either a wheel was rebalanced at some point, or they are from a different car. See attached photo I just took of my RS 5 wheel for the zinc wheel weights used by the factory.

I bought the set of four 18" Audi wheels from the dealer here in CT. So the weights aren't factory, but dealership installed.

I'll get the wheel rebalanced if I can feel a difference when driving.
