Throughout the game, the player can unlock various brick sets and character pieces by completing certain tasks, such as coming first in a Circuit Race. The game's "Build Menu" allows the player to build custom cars, minifigures and driving licenses of their own design using unlocked bricks and character parts. Minifigures can be customized with different hat, hair, head, body and leg parts, and given a name entered by the player on the minifigure's driving license. A picture of the player's minifigure is also placed on their driving license, and their facial expression can be changed by the player. The player can create a custom car using a combination of different chassis and car sets. The player can rotate, move and place bricks from these sets directly on to the chassis. Placement of the bricks changes the car's balance and weight, which affects its overall performance. The "Mix" option creates minifigures from randomly selected parts, while the "Quick Build" option creates one of 2 presets for a specific chassis.
