I have tried stock 4K then 2 gears (too much rotation for me and less stable) then was advise to thicken the diff. Now 7k and will try 10k.
Seems more stable and consistent but we run mod on very bumpy astro with a low ride height.
I'm guessing the higher the oil the less diff out so the car is more stable at speed on bumpy section
