How we work these out
These are not simulated or estimated figures. Every lap time here was set by an Apex Racing Academy coach on the Apex setup for that car, in the same session conditions, and published as a VRS data pack. The fastest lap is the quickest complete lap driven. The optimal lap is that driver’s best sectors added together — what the car had in it on the day.
We publish this every week of the iRacing IMSA season, for every car in the class.
