Oh, I am subscribed to this thread - don't you worry!
I am going to build an emaxx and have been lurking off your thread and others to see just what type of setup I want. Still researching...
But I did pick up a FLM chassis, hybrid bulks, shock towers (pretty much your setup) and some HB diffs - still waiting for the 43t diff gear (HBSC8028) to swap with the spirals that came with mine. Damn things are sold out
EVERYWHERE.
But I can't wait to hear how the slipperential is in the maxx. It just might be my next part....
