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 one of these for every special event, and every week of the IMSA and GT Sprint seasons, for every car in the class.
