I discovered something very unfortunate: Notice the issue?

All this time I assumed your car has an LSD. No??
What was once an LSD is not an LSD for ever.
Good thing I have a nice, known good (because I tested it), S3.25 on the shelf.
I will probably just throw this one in the car as-is (if i can get to it today or tomorrow) and then rebuild the one in the car for later.
Based on the above, I set about scheming to drop the S3.25 in while I fixed the diff in the car.
But last week there was another thread about Torsen diffs and Z3Ms. It got me thinking. Which is rarely a good thing.
I remembered that Vlad's S3.23 came from a 2003 Z3 M-Coupe. Which is a Torsen diff. It occurred to me that Torsen diffs don't act like clutch-based LSDs, especially when there's no resistance. I don't actually know how a Torsen diff works (I barely understand how a clutch-based LSD works), so don't ask me.
So this afternoon I did a different test:
Yup. Torsen differentials behave like open differentials when no forces are applied. So there, in fact, is nothing wrong with Vlad's differential.
In other words, Vlad remains perfect.
