This Forza Horizon 6 race customizer guide explains how to unlock the feature, change an existing Festival event and create practice, testing or Convoy races without building a full EventLab route.
Race Customizer keeps the original course but lets you reshape its conditions, opponents and eligible cars.
Unlock Race Customizer
Complete a supported Festival event once, return to its marker and open the Event Setup menu. Race Customizer unlocks separately for each event, so finishing one race does not activate it across the whole map.
Playground Games confirms that the available race-condition controls include up to 11 Drivatars, season, weather, time progression, laps, Rewind, camera lock and traffic
Choose Race Customizer, set the rules and launch the event again. It is ideal when you like the existing course but want different cars, weather or race conditions.
The wider FH6 multiplayer activity selection is more useful when you want a completely different competitive format rather than a modified Festival race.
What Each Setting Changes
| Setting | Main Use |
| Drivatars | Set up to 11 AI opponents |
| Season and Weather | Practise dry, wet or snowy conditions |
| Time of Day | Run the event in daylight or darkness |
| Time Progression | Let lighting change during longer races |
| Laps | Create short sprints or endurance sessions |
| Rewind | Allow learning runs or disable corrections |
| Camera Lock | Create cockpit-only or fixed-view challenges |
| Traffic | Add pressure or create cleaner practice |
| Car Theme | Apply a ready-made class or vehicle category |
| Individual Cars | Build one-make or rivalry events |
| Route | Remains tied to the original Festival event |
Change only the rules that support the event’s purpose. Combining heavy rain, night conditions, traffic and maximum opponents may be entertaining, but it makes testing less useful.
Set Fair Car Restrictions
Race Customizer first selects a Car Theme that matches your current vehicle. You can keep it, choose another preset theme or permit specific cars.
Class-based rules create a varied field. Individual-car selection works better for one-make racing or direct comparisons. Avoid mixing vehicles with very different stock classes unless every driver uses an agreed build target.
Consider whether the original route rewards acceleration, cornering or loose-surface grip. The strongest FH6 cars for different race environments can help you choose models that suit the course instead of filling the grid with raw top speed.
Each participant still needs an eligible vehicle. When the event is restricted to a limited reward or exclusive model, available hard-to-find FH6 cars may provide another acquisition route.
Four Event Setups That Work
Clean Practice
Use one or two Drivatars, dry weather, daylight, Rewind and no traffic. This keeps the track clear enough to learn braking points.
Tune Comparison
Keep weather, season, time and lap count fixed. Consistent conditions make tire, gearing and suspension changes easier to compare.
Convoy Mini-Series
Choose several completed Festival events, apply the same class or theme and use a short lap count. This creates a simple private championship without designing routes.
Challenge Race
Lock the camera, disable Rewind or add changing weather. Introduce one difficulty rule at a time so the event remains demanding rather than random.

Routes, Convoys and Sharing
Race Customizer changes an existing event; it does not redraw checkpoints. Use EventLab when you need different roads, placed props or a shareable custom blueprint.
For group play, the Convoy leader opens the event and applies the settings. Other members join under those conditions.
Cross-platform groups should form the Convoy before entering. The FH6 crossplay session setup covers the platform and connection details that matter when an invitation does not appear.
Troubleshooting
- Customizer is missing: Complete that specific Festival event once.
- A car cannot enter: Check the class, Car Theme and permitted-car list.
- Friends receive different rules: Let the Convoy leader create and start the event.
- The course will not change: Use EventLab for route creation.
- Weather or traffic is wrong: Reopen Event Setup and confirm the selections.
- Someone owns no eligible car: Broaden the restriction to a shared model or class.
Final Takeaway
Use Race Customizer when the course works but the original rules do not. Unlock the event, choose one clear purpose and change only the settings needed for that race.
