New: Car Class Grouping by Car Number
Running a custom league or special event in iRacing? We've got something for you. ๐
RaceLab now supports a new Car Class Grouping option: Group by Car Number (hundreds).
How it worksโ
This option groups cars based on the hundreds digit of their car number. For example:
- Cars #100-199 are grouped together as one class
- Cars #200-299 form another class
- And so on
This means league organizers and event hosts can define custom class groupings simply by assigning car number ranges - and RaceLab will automatically pick them up and display them correctly in your Standings and Relative overlays.
Why this mattersโ
In official iRacing series, car classes are defined by the sim itself. But in custom leagues and special events, organizers often create their own class structures. Until now, RaceLab couldn't always group these correctly. With car number-based grouping, your overlays will show the right classes as long as the event uses number ranges to separate them.
How to enable itโ
- Open RaceLab and go to Settings
- Look for the Car Class Grouping option under iRacing settings
- Select Group by Car Number (hundreds)
- Your Standings and Relative overlays will now group drivers accordingly
Perfect for endurance leagues, community events, or any race where custom class structures are used. Let us know how it works on Discord!
