I have two questions about my rear counterweight
I measure the distance between my fingers to confirm that it is a S5 rear counterweight?

There's no real way to discern the difference between the two?
In fact, I heard a rumor that if you order a new counterweight from Mazda, the part is identical for all FC years and the part #'s are identical - the new counterweights are NOT drilled, and you had to get them balanced yourself???
As a general rule for the counterweights - the S5 had more holes drilled in them versus the S4.
I weighted them once, and the difference was 0.2 lbs., which was the increment on my 100lbs. max digital scale.
So I think the difference will be a matter of ounces and even down to grams...?

I believe that this wear is fine, but need to make sure

Is that a groove (black line) in the counterweight???
I have NEVER seen a groove worn into the metal like that in my life.
Did you get an explanation for the groove?
That might wreck the rear oil seal?
