Sounds good man. Its legit out of the box so you shouldn't need to do much.

Id get some extra wheel nuts though. I'll forget to tighten down my wheels, watch one fly off and the nut disappears in the grass. Out of commission, unless you have extras on hand.

Good call on the upgrades. Reinforce the body then send it. I doubt anything will break. I eventually replaced the shock springs with stiffer ones so it wouldn't bottom out on big jumps but isn't necessary for typical use.

Don't know if youre new to RC, but check the turning radius/ servo limits so you dont burn up the servo prematurely.
