RaceWarz has a Parts Department available to boost your cars' performance. You can choose from different categories of parts, and once you purchase one it is automatically equipped. To unequip that part, you can go back to it's category and click unequip. There are also Equip All and Unequip All buttons on the main Parts Department page. Like the Car Lot, prices and stats of the parts listed have been inflated for game purposes. And you shouldn't rely on them for real life purposes.
