A new/better steering servo is always good too. I put a 645mg in mine.

And get drive shafts as well. Front and back. I managed to get mine to pop a wheelie when it hit second and shortly after on a small jump the rear drive shaft snapped.
I blew the rear diff as well. My fault, my tires where bald and not even so that caused the diff gears to give out just like it does in 1:1 AWD.
