There are five available vanity item options that can be applied to cars; nitrous colour, tyre smoke, underglow, air suspension, and horn.
They can be found in the garage under the "Vanity Items" section of a car's customisation options.
Nitrous colour items offer a selection of colour options and will change the colour of the nitrous flames that fire out a car's exhaust tips.
Tyre smoke items offer a selection of colour options and will change the colour of any tyre smoke emitted from a car whilst drifting or performing a burnout on tarmac.
Dust kicked up when off-road will not change colour based on any applied tyre smoke items.
Underglow items include a selection of coloured neon strips that are applied to the front, rear, and sides of a car.
Equipped underglow items are only visible at night and are difficult to notice during the day.
An air suspension item can be applied to a car and will equip air bag kits to a car's suspension.
Stopping a car and turning off its engine with an air suspension kit equipped will lower the car's ride height.
A horn item can be equipped and will change the audible horn sound that is emitted from a car.
The selection of horn items available includes different tones and melodies that can be activated by pressing or holding down a car's horn.
