The Pro version really doesn't need much in the way of upgrades. You may need a bit stiffer springs if you run a heavy battery/motor combo. The spur gear should be just fine as long as you are running the RC-Monster hardened pinions. Drop Mike an email, ask him if he has a motor mount for a Muggy (see this post). The Muggy center diff is exactly the same as the Sportwerks.

The center diff mount for the muggy and turmoil is the same? If this is confirmed and Mike has the mounts available I may pick one up.
