Against the front of the class, by track and class
| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Virginia International Raceway (3.27 mi) | T4 | 5 | +10.568s (8.11%) | +9.869s (7.43%) |
| Unknown track (3.27 mi) | T4 | 3 | +8.583s (6.53%) | +7.481s (5.73%) |
Gap is the driver's best lap in a session against the fastest lap in their class in that same session (zero is fastest in class), shown as time lost and as a share of the lap, so conditions cancel out and tracks can be compared. Typical is the median session.
