aluminum driveshaft and bearings

[inventor210]

1) aluminum driveshaft (depends on the motor. anything over a black can put it in)
2)desent set of tires (depend on what you are doing with the car. if on carpet try hpi race compound x patterns)
3)rear toe blocks (1 deg)
4)bearings
5)rear bumper (if racing use the bumper. it will save you bodies alot)

Is the car you bought a kit version or an RTR
