Thicker front diff oil is supposed to increase on-power steering when using a center diff. I thought that I was getting more on power when I went lower, but I think I may have misunderstood what I was seeing as "better cornering" in general and I as actually getting more turn in.

What do you guys think? seems like on-power was getting lost more to rear weight transfer to me.
