I've been racing my M03R for nearly 2 months. It is a great car, and the out of the box setup is also very good! All you really need to buy are some universal joints and a ta03 ball diff (if you like ball diffs). I would advise you to also buy a black or grey chassis, there really is no point running the chrome chassis as it will flake everywhere. After each race everytime you brush the dust off chrome will also brush off too
