Against the front of the class, by track and class
| Track | Class | Sessions | Typical gap to class best | Closest |
|---|---|---|---|---|
| Sebring International Raceway (3.74 mi) | STL | 9 | +17.067s (11.79%) | +11.740s (7.86%) |
| Pittsburgh International Race Complex (2.78 mi) | STL | 6 | +8.111s (6.94%) | +6.842s (5.74%) |
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.
