Optional parts for Outlaw Rampage and replacement parts for Outlaw Rampage PRO. Roll cage includes one spare tire (same as used for driving) that completely transforms the scale realism of the model. Two arrangements for spare tire mounting are possible which alter the length of the chassis and weight balance to affect rear grip; single tire horizontal mount, and twin tire vertical mount. Spare tire arrangement plays a functional role in running stability as well as recreating realistic scale appearance.
