Jack,
I have LSD spec'd for my car and when I tried Redline NS 75W-90 it chattered, so I put some LSD additive in it and it's fine. However, I noticed this summer when it was in the air that when I rotate a rear wheel forward the opposite one rolls backwards. I thought if the car had LSD they'd both roll forward. So I'm wondering if that indicates worn out clutch plates and inoperative LSD?

The LSD option is very rare. My shop averaged between three and five 911 service/repairs a day and we could go months without seeing one with LSD. SOP was to turn a rear wheel before re-filling the trans so we would know to add the LSD additive. Properly cared for the system is extremely reliable, we repaired very few of them.
