LC Racing EMB-T: Do you need to shim your diff?

It's a common issue with the LC Racing EMB series RCs where the outer diff gear and the bevel gear get chewed up pretty quickly due to fitment issues. It appears LC Racing fixed the issue with the HD Diff with a nice a snug fit but just in case yours doesn't, you will want to shim it.
Checklist
1. No play between the diff in the case diff.
2. Slight play between the bevel gear and outer ring gear (similar to meshing a motor pinion/spur)
3. No resistance/grinding when you spin the diff
I'm order to properly shim, you need to pass all 3 checks above.
