Customization of your cars is where the real fun lies. Each car has a certain number of slots that can be filled with weapons. Shotguns, machine guns, mines, smokescreens, and more are all available to be installed on your racing wagon. Most can be placed anywhere though some weapons, such as mines or the smokescreen, must be rear mounted. Achieving that perfect custom combo that works for you is key to winning races later in the game.
