This track has been raced on 2 configurations (19, 2.92 mi; 3.02 mi). Laps on different configurations are not comparable, so only events on the 2.92 mile layout are shown; switch above to see the others.

FE has no laps in the events chosen. It ran at Super Tour Apr 2019, Super Tour Apr 2018, Super Tour Apr 2017: add those events.

SRF has no laps in the events chosen. It ran at Super Tour Apr 2017, Majors Apr 2016: add those events.

Sectors are not comparable across all of these events. Sector times and the theoretical lap use Cal Club 2022, Cal Club 2024 only. Super Tour Feb 2020 (sectors cut at different points) counts towards whole-lap times and trap speed only.

2 laps are left out as timing errors (far too short to be a lap of this track). The rest of those sessions, sectors included, is used.

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

S1 SF → IM1
S2 IM1 → IM3
S3 IM3 → SF
SPd IM2 → IM3 0.02 mi

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

2024-01-01 FE FE/FE2 rule update

#35269 from Robey Clark · Rule change · TB 24-01 (2024-01 Fastrack)

wordingFE allows racer's tape for crash repair, panel security, and heat exchanger opening control; seam taping banned.

As printed in Fastrack

In FE, GCR section 9.1.1.I.2.P.c, add the following:
"Racer's tape may be used to repair crash damage, or as a precautionary means of securing the body panels or
retaining l~~atches~~ fasteners only. Crash-damage is defined as having occurred during the current event, and the tape should be of
an appropriate color if possible. Taping of body seams is not allowed. Taping across heat exchanger openings as a way to control
temperature is allowed and may serve no other purpose."

What the rules allowed changed as listed; this does not say what any particular car ran.
