SCX10 Dingo Kit Dual Motor Mount
 

I plan on doing the following mods and was needing help on gearing for it.

I will be installing the dual motor mount and running 55t motors. I would like to keep the engine cool while running. I am looking for more torque to get over terrain and still keep enough speed to make good time between gates. What gearing should I get.

I will also be upgrading the drive shafts and gearing with hardened steel and upgrading to 2.2 tires, 100mm shocks, and dual motor ESC and 3s Lipo.. Any advice would be helpful
