and you are going from kit gear diff, to ball diff.
why would you do that?
On very high traction situations, you can use a gear diff with no issues. On less traction situations like a prepped parking lot track, the ball diff provides more rear bite.
I would test both and see what you prefer. Here in Socal, this is what we have found, over and over again to no fail.
