So, I started the build...

First up is the rear bulkhead.  I replaced the stock plastic bulkhead with a nice purple aluminum one.  



A little bling-y yes, but it's rigid and it's metal so it should stiffen the chassis as well as help further dissipate heat heat when attached to the purple finned motor mount:



Now the motor mount is a little harder to justify as a performance mod as it has less surface area than the stocker.  But, it's thicker and it's finned.  The fact that it's shorter could lend to a lower center of gravity, mebbe?  :sweat:  

That particular motor mount was destined for a Pro2.  I actually had it a while; it was from an old build.  The marks around the pinion opening are from when I hit the throttle, but hadn't screwed in the motor well... :sweat:

I had to file off the lower screw hole as it wouldn't fit on the MT chassis with it on there.

Next is the belt tensioner.  Aside from looking awesome, the stocker was plastic and the actual tensioner portion would wear over time and and not hold the belt very tight over time.



And the completed halves of the rear bulkhead:
