A full grid of GT3 race cars from many different manufacturers lined up in a staggered double file, receding into low golden-hour sunlight.

01 — Calendar

Season schedule

Every round runs the same format, so the calendar is really a progression of circuit character — from Monza's slipstream draft to the concrete of Mount Panorama.

    02 — The field

    The GT3 grid

    Setups are fixed and the cars are balanced, so what separates them is shape: where the engine sits, how long the bonnet is, and how that plays at Monza versus Bathurst.

    Engine layout

    Car images are locally generated impressions of each silhouette — not photographs of the real cars, and the liveries are invented.

    03 — Event format

    How a race night runs

    Identical at all ten rounds. The mandatory stop must fall inside the green-flag window between minute 10 and minute 25 of the race.

    Session timeline

    Total on-track time, minute by minute.

    Round 8

    Night Sprint — Daytona

    Oval banking drafting battles, dynamic night lighting braking cues, and precision through the Bus Stop.

    04 — Championship

    Points structure

    Points are awarded to the top 20 finishers, plus two bonus points available each round.

    Points by finishing position

    Steepest at the front — a win is worth more than 4th and 5th combined.

    Bonus points

      Drop weeks

      Best 8 of 10 rounds count toward final standings, so a driver can miss two races or write off a DNF without losing the title fight.

      Exception: a race lost to disqualification for intentional wrecking or severe misconduct cannot be dropped — it counts as zero.

        05 — On track

        Pit stop & race rules

        • Mandatory stop window

          At least one pit stop during green-flag conditions, between minute 10 and minute 25.

        • Service requirement

          The stop must take at least 1 litre of fuel or change at least 2 tyres.

        • Pit lane speed limit

          Strictly enforced by the in-game automated penalty.

        • Fast repairs

          One fast repair per race session.

        • Setups

          Fixed for every round — the field runs identical cars.

        • Qualifying

          Open 15-minute session; pole is worth a bonus point.

        06 — Stewarding

        Incident limits & penalties

        Incident points are policed automatically in session. Anything the sim does not catch goes to the stewards.

        Post-race stewarding & appeals

        Protests can be submitted via video clip within 24 hours of the race.
