Spawn a car you own and open the gear icon on the driving interface. Changes apply to that car. The menu splits into handling and cosmetics. Doors are not an interaction. You are placed in the seat.
Handling
Drivetrain choices are all-wheel drive, rear-wheel drive, and front-wheel drive. All-wheel drive is the setup described for keeping a powerful car straight and for donuts without an instant spin.
Suspension height raises or lowers the body. Suspension stiffness softens or hardens the springs. On a stock Bugatti Bolide, lowering the car and changing stiffness moved handling from 29 percent to 54 percent and changed acceleration by about 0.1 second. Top speed is not what that test improved. The gain is corner speed on Circuit and the opening bends of the Highway.
Paint, skins, and rims
A color wheel sets exterior paint. The Galaxy skin is priced at 50,000 Cash. Blue Money is another named wrap. Its price is not published. Rims in the notes include styles referencing Bugatti, Koenigsegg, Centodieci, and Hennessey Venom. Some gloss and satin sections are fixed to the model and are not a paint option.
Passes that sit next to this menu
Car Radio is 20 Robux and plays audio while you drive. Nitro Customization is 80 Robux. Its catalog description is blank, so the nitro options are not listed outside the game.
Tune before a Circuit session if the car's handling is under the 80 percent note in the race guide. A Highway car can stay taller on speed and still needs enough steering for the first corners.
The game description says vehicle designs are not an endorsement or license from any manufacturer. Several shop cars use original names. Community stat pages still use real brand names for some models.
