I want to say thanks for all the info from this thread.

I finally got my truck feeling good to drive on a medium size indoor high traction track.
This truck is a blast to drive, however I'm working on tuning out some of the twitchy feeling I had from the front end. I was running the diffs as factory with the cheap grease in them.

I tried 50k in the front and the truck pushed really hard into the corner if I used any kind of power. I think I may dial it down a bit and go with 10k in the front to try it out. I'm looking for a setup very similar to stock, but I want the front end to push just a tinny bit.
