Question about the V.3 hybrid revo diffs

[doo540]

just did a test fit of mine, the ring gear rubs slightly when dropped into a empty case.
I'm not worried about that, did you guys shim your gears beyond the stock setup? Mine feel slight notchy, I didnt over tighten the case, and I also dont have any grease on the ring/pinion yet. I would assume they might need slight shimming to get perfect.
