Wow, you went full in!
The only thing I've done so far...is shocks. Got the blue AE ones. Mainly cuz I'm a suspension nerd. But totally stock otherwise. I do want to mess with the diff weight oil. But that's on the bottom of my to do list.
No, wait. alum motor fin. And made sure the body allows for a lot of air. Other than that? I don't even run a fan. But the electros did "error out' before doing the fin and body cuts.
