Cen diff upgrade

[Nard Cox]

Here another Cen Diff mod showcase.

But I wouldn't go for Cenns now the HPI Bulletproof Diffs are out and they are selling for only $25 per set. Only heard positive stories so far. People say they are almost like Cen Diffs only with better machining quality (HPI > Cen).

I'm currently also running the Cenn Diffs because the stock diff pinions broke (both front and rear at the same time) and they are holding up fine so far.
