DB01 upgrades for brushless?

[kaszal]

I'm helping a friend hop-up his DB01 Durga so it can handle brushless and I need advice on the upgrades. I've looked through a lot of threads and there seems to be a bewildering array of bits on eBay.

Are these the essentials?

slipper
3Racing diff outdrives
ceramic diff balls
front universal shafts
hex screw kit
suspension mounts and blocks 54037/8/9
possibly 501x dampers, fast servo and alloy steering

Are the reinforced belts neccessary?

Any advice welcome. Thanks.
