E Revo Center Diff questions and Opinions

[mistercrash]

I am pretty sure that all good diffs and center diffs like Ofna, Thunder Tiger, Losi, Mugen and so on use hardened steel spurs and ring gears. That CD is starting to look good simplechamp, if that lip is still too thick and you run into fitness problems in the tranny, you can take off a little more and I'm sure you won't have any problem. The lip I left on my CDs are like half a millimeter thick, it's just there to center the piece on the diff case.
