Cheap Granite diff upgrade
It has a card in the box that says it's "brushless ready" well mine definitely was not. After maybe 10 minutes of running it sheared of three teeth in the front ring gear. Amazon specials to the rescue, about $50 for the pair. The internal gears from the factory diff went right in. I used the included steel pinions from the kit, and saved the stock ones as spares.
My brushless setup isn't crazy either, 2s, Hobbywing 10BL60 and Castle 3800kv 3650 (The motor does seem spicy though)
