The Rulebook
Common sense and real racing.
Plain English, one topic at a time. This is the whole thing.
v1.7.0 · Published September 26, 2026 · No changes since September 26, 2026
- Sep 26 (v1.7.0): Calendar reset, sealed by Jon — thirteen nights: Preseason Oct 25 at Dragon Trail, Wk 1 through Wk 10, Christmas off Dec 27, Playoff 1 Jan 17 Mount Panorama, Playoff 2 Jan 24 Spa; Suzuka leaves the season. Every week keeps its car, laps and settings. Preseason rank is the preseason night’s points, Main finish as tiebreak; the preseason Opener grid is a logged random draw. Kickoff-party and returning-priority dates retired: seats stay open until sixteen are paid.
- Sep 7: Main event: at least two tire compounds, so at least one pit stop (Mandatory Tire Types 2).
- Sep 7: Modifications: no nitrous, no Extreme upgrades, no wide-body kits, no engine swaps; everything else under the PP limit.
- Sep 7: Lap counts are final.
- Sep 7: No wind rule. Nothing about wind is asked, read or checked.
- Sep 7: Qualifying takes screenshots only — the site reads your lap, PP and car; you confirm.
- Sep 6: Gr.4 limit 675 PP, Main limit 775 PP.
The night
Every Sunday is a Night. Lobby opens 2:45 PM Central; the first race is at 3:00. Each night has three Events: the Opener (~15 min, identical car for everyone, stock plus racing medium tires), the Gr.4 (~20 min, pick from the shared pool), and the Main (~30 min, Gr.3, the longest race).
Openers and Gr.4 run fixed clear weather with no tire wear or fuel. The Main runs tire wear 5×, fuel 6×, refuel 10 L/s, mandatory tire types 2, and random weather every night.
Main event: you must run at least two different tire compounds, so you’ll pit at least once. Racing Hard and Racing Medium both work on Gr.3.
Rain is possible only where GT7 supports it: Red Bull Ring, Fuji, Nürburgring GP, Tsukuba, and Spa. Everywhere else, random weather changes the sky, not the grip.
Scoring — one curve, three scales
Finishing position pays the same shape in every event: the Main at full value, the Gr.4 at 80%, the Opener at 60%. Published integers — the engine never computes percentages.
Mover of the Night: +10 to exactly one driver — the largest combined positions gained across the Gr.4 and the Main (start minus finish, summed; the Opener is excluded). Tiebreak: better Main finish. A Ghost Sub cannot win it.
Drop weeks: the best 8 of 10 regular-season weeks count. In-season standings show raw totals; drops apply at the end of Week 10. From Week 9, both a Total and a Counted column are shown. Standings ties break on preseason rank.
Qualifying
Each week every driver runs a five-lap time trial at Sunday’s track in the Gr.3 car they will race in the Main, tuned to that week’s PP limit including any personal cap. Shortcut penalties on; the fastest of the five laps counts.
Submit on the site by Saturday 2:00 PM Central: the lap time, a screenshot of the five-lap session, and a screenshot of the car’s PP and settings screen. Submitting locks that Gr.3 car for the Main. Qualifying order sets the Gr.4 grid; the Gr.4 finishing order sets the Main grid. Miss the deadline or submit an invalid run and you start the Gr.4 at the back, in last week’s finishing order.
The PP handicap
Applies to the Main only, Weeks 2 through 5. No handicap in Week 1; preseason plays no part. The Main has a fixed PP limit of 775; the Gr.4 runs at 675 with no handicap. Entering each week from Week 2, the standings leader carries a personal cap of the limit minus 30; 2nd −25; 3rd −20; 4th −15; 5th −10; 6th −5; 7th and below unrestricted. Enforced by the PP screenshot in Saturday’s qualifying submission.
Jon decides at Week 6 whether to keep, escalate, or drop it.
Ghost Sub
A substitute races so the grid stays at 16, invisible to points. For scoring the sub is removed and every regular below them moves up one place, and the absent driver scores 0 for the night. Absences are declared by Thursday and RSVP is due Saturday noon — an undeclared name in a results screenshot is a validation failure, not a guess.
Stables
Four-driver groups formed at the draft, each with a captain and a name. Each night a stable scores the sum of its three highest-scoring drivers (the fourth is dropped for the stable score only). The Stable Champion is the top stable after Week 10 (regular weeks only). The playoffs are drivers only: the top 8 after Week 10 race the two playoff nights on a clean slate. Drivers 9 to 16 do not race the playoffs.
Cars & modifications
Modifications: no nitrous, no Extreme-category upgrades, no wide-body kits, no engine swaps. Everything else is allowed under the PP limit.
Main event: you must run at least two different tire compounds, so you’ll pit at least once. Racing Hard and Racing Medium both work on Gr.3.
Lobby settings
Money
$100 entry via Venmo @jonzimmy, note “IFRL”. Pot $1600. Stable champion $400 ($100 per driver). Top five drivers $500 / $300 / $180 / $120 / $100. Optional shirt $65, due Oct 1. The site processes no money — payment is a Venmo link and QR.
Practice lobbies: Wednesdays 7:30 to 9:00 PM Central; Saturdays 8:00 to 9:30 AM Central.
One restart
A race lost to a lobby crash or host disconnect is rerun once that night. If it cannot be, nobody scores it. Keith holds a saved copy of every lobby setting.
The screen is final
Whatever the results screen shows is the result: finishing order, penalties, contact. No incident form, no appeals, no points penalties. Foul play: tell Jon privately, Jon has a quiet word, it ends there. The one exception is the captains’ spirit ruling below.
The spirit of the thing
This league is governed by common sense and real racing. The game will let you do things a real car and a real driver never could: ride a wall to hold a corner, carry speed you’d never survive, use a barrier as a slingshot. If a move would wreck the car or put a life at risk on a real track, it doesn’t belong on ours. When a driver races that way on purpose, any driver can raise it with the captains before results go final on Tuesday at 9 PM Central. The captains vote. If they decide it went against the spirit of real racing, that driver’s results for the week are removed. This isn’t about hard racing or honest mistakes. It’s about the difference between racing and playing a video game.
Mechanics: a majority of the four captains decides; a captain does not vote on a driver from his own stable; ties go to the driver; the challenge must be raised before the Tuesday 9 PM Central cutoff. A removed week scores 0 for the driver and for the stable’s count, and uses one of the driver’s drop weeks.
Refinement window
Rules may be refined after the preseason night. They lock before Week 1 (Nov 1) and do not change after. This page shows the version, the publish date, and the “No changes since” line above.
