This track has been raced on 2 configurations (The Circuit, 2.57 mi; 2.92 mi). Laps on different configurations are not comparable, so only events on the 2.57 mile layout are shown; switch above to see the others.
One row per driver and car (a driver who changed cars has a row for each). Each cell is that driver's best in that car across the selected events, with the session it was set in. Best 5-lap stint is the mean of the driver's quickest five consecutive race laps, and consistency is how far their median race lap sat behind their best in that race (small is a driver who does it every lap); both come from the race with the best stint. The fastest in each column is purple, and a car whose best lap is more than 115% of the fastest in its class is greyed (marked ">115%" beside the driver) and left out of the colour scale. Click a column to sort, a row to highlight it.
Theoretical lap is the sum of the best sectors, whichever laps they came from, and never slower than the best lap (where a car's fastest laps were recorded without sector times, its best lap is used). The 115% mark is about the car's best lap only: a car whose best lap is within 115% of the fastest in its class is never marked. Greyed sectors with no theoretical lap mean the sector times on file do not add up to a believable lap. Letters refer to the events above; Q is qualifying, R a race.

Sectors are numbered in lap order from start/finish, whatever each event's timing called them; the loop names are SCCA timing's.

#39281 from Jay Messenger · Rule change · TB 26-01 (2026-01 Fastrack)
neutralFF clarifies alternative tire eligibility for cars homologated 1989 or earlier with rocker arm or outboard suspension on all four corners.
In FF, GCR section 9.1.1.B.10.e, change as follows: "Alternatively, Formula F cars with rocker arm suspension (e.g., 1987-90 Reynard, Swift DB1,) and/or outboard suspension on at least one chassis end homologated in 1989 or earlier with any combination of rocker arm or outboard suspension on all four corners (e.g., 1987 – 1990 Reynard, Swift DB1) may use the following alternative tires. Note: This rule is intended to allow older cars with the described suspension design to use the alternative tires. It is not to be exploited by modifying cars with push-rods or pull-rods to meet the above requirements or by modifying either end of older cars to push- or pull-rod suspension to be eligible to run the alternative tires. Cars that were homologated in 1989 or earlier with push- or pull-rod suspension on no more than two corners may seek approval to run the alternative tire by utilizing the compliance process outlined in GCR section 8.1.4."
