No Ceramic diff balls, not essentially needed and expensive. Also the alloy steering is not important. A friend races his DB01R with normal steering and since 120 Lipo charges it is still fine.
Get the slipper, outdrives, alloy suspension bits and the belts, or do it like super gripper proposed: buy a DB01R and take the Durga for spares, it will be much cheaper plus you will have this car for a very long time!
