To me, this disc looks burnt to hell in one ring, and new in the rest?
I think I have a Sachs disc I can still read the numbers on, I'll dig that up later.
Where was the red powdered metal coming from?

I'll re-do my test and have someone watch both rear wheels so I know exactly what's happening.
You can see the clutch kit above that I used so I'm thinking it's just an incorrect test I performed.
That burnt clutch disk was the one I took out of my "new" 1983 745 which had 203,000 miles on it and the used car store I bought it from had purchased it from a guy in San Francisco. Based on my pictures of the throw-out bearing and wear on the original pressure plate spring contact point I would say that clutch got used a lot.
About the red powered metal....I'm not sure. I think it's just a mixture of clutch disk dust and flywheel/pressure plate dust combined with the Bay Area moisture.
