Race Customizer unlocks for a race after its first completion. Use it to change a replay’s rules and conditions; it is different from creating a new route in EventLab.
Complete the original event first
The official campaign guide describes a per-event unlock. If you cannot customize one race, check whether that particular event has been completed rather than assuming completion of a different race unlocks every route.
Suggested practice replay
Choose settings that support one learning objective.
- Complete the selected race under its original requirements.
- Open that event’s setup and inspect the available customization options.
- For route learning, choose conditions you can repeat consistently.
- Adjust one factor, such as weather or lap count, and explain to yourself what it will test.
- Keep notes of the setup when comparing results with a later replay.
A custom replay is not proof of seasonal eligibility
A Festival Playlist can require its own event and car conditions. If your goal is a reward, enter from the relevant tile and confirm its rules. If your goal is a new route or obstacle course, choose EventLab instead.

Does changing an event make it a new EventLab creation?
No. Editing a replay’s conditions and designing a new event are separate workflows. Use the tool that matches your actual task.
