First mod was add King Headz locking wheel nuts (didn't like the oem traxxas nuts w/ loctite). Then some cf completes the exterior look.
Next up is the battery expansion kit, 9000mah and 60c of power =). Twin 4s in parallel. I don't really need a 100mph, so with the 4s it should hit about 70mph and run time should be great. Side benefit is the car got heavier, so it should never flip. Weigh's 10.5lb with the two 4s 4500's.
