Here's a question for anyone to respond too... Recently I built my D413. I have about 6 runs on the car. I pulled out the front and center Diffs to change the oil for tuning. And the oil was really dirty. I guess my question is... Is that normal being the first oil change? And how often should I change/ freshen up the oils in the diffs?
