So we all know that the stock front diffs aren't that strong. I'd like to swap in a Euro M3 3.0L motor into the car which is 282hp. My center diff is dead right now and needs a rebuild. I was thinking, if I rebuild my center diff and refill it with a lower viscosity fluid, would that cause it to slip more and reduce the drive on the front diff?
