I have no idea what that car is.

Well I am assuming you have a sway bar kit. Probably have some shocks already. Maybe get yourself a motor cooler the fin type. Well that is if you don't have it already. I can't think of anymore hop-ups for the m03 off hand. I am also not sure about the motor cooler. A few friends run them & recommened them is my motor gets warm. Mine does so I am think about trying it out. Tires & rims have some extra. Faster steering servo unless you have a fast one already. There not needed a basic servo works fine. This would be some what of a hop-up.
