The player profile can be customized with panel, banner and accolade images, which are shown above cars at the start of a race. These are unlocked by completing races and achieving certain goals, e.g. achieve the highest speed, become 1st place, draft the longest etc.

There are limited possibilities for changing a car's appearance. At this time it is only possible to chose from a selection of liveries and modify their colours. The presets each have areas with various surface effects (matte, metallic, glossy), which are not customizable unlike in previous GRID games. Some liveries, like Heritage 15, can be utilized to create liveries with a uniform colour and surface.
Liveries are categorized into Common, Rare, Epic and Legendary. Some cars have limited options for livery customization (for example the Nissan Skyline GT-R Group A (R32)), and on most cars some categories of liveries to chose from are based on their grouping.
Wheel design and size can not be changed.
In preparation for a race you can tune a car's suspension, transmission and break bias settings.
