iRacing 2026 Season 1 Patch 2 update

We’ve logged the main changes in iRacing’s 2026 Season 1 Patch 2 notes. This patch focuses on GTP tire and car updates, UI fixes, telemetry additions, and a few important rules changes at specific tracks.

What changed

Fixes

UI: the "iRacing" driver flag conversion to "Global" is complete.
UI overlays/widgets: fixes for timing column widths, duplicate spotter text settings, license display when the black box is collapsed, position saving with scaling override, Time Trial info in Lap Timing, and clock widget visibility.
ARCA Toyota Camry: fixed a paint pattern appearing fully black.
Dallara IR18: fixed a flipped driver-side aeroscreen decal.
Sebring: fixed a visual issue with some light poles at certain camera distances.
Dallara P217: fixed opponent cars incorrectly appearing to ground and throw sparks.
Toyota GR86: fixed missing side mirrors on opponent cars.
Lånkebanen (Club): fixed an issue where lap times sometimes did not count correctly.

Cars

AI racing: improved AI performance with the Mercedes-AMG W12 E Performance and the GTP class.
GTP class: now uses Vision tread tires debuting next season, with updated tire properties.
BMW M Hybrid V8: slightly increased fuel burn rate; iRacing setups updated.
Acura ARX-06 GTP: slight aero changes, 5 kg weight reduction; iRacing setups updated.
Ferrari 499P: updates to vehicle and tire properties including aerodynamics, brake cooling, engine braking, MGU friction, brake pedal force demands, rear suspension geometry, and a 10 kg weight reduction; engine cooling, fuel burn rate, and aerodynamic parameters also adjusted slightly; iRacing setups updated.
Porsche 963 GTP: iRacing setups updated.
Cadillac V-Series.R GTP: spinning tire texture updated; iRacing setups updated.
NASCAR Xfinity Series: rear bumper hull stiffened and rear bumper yield limits increased in the damage model.
FIA Cross Car: wheel breakage threshold increased in the damage model.
Porsche 911 Cup (992.2): steering wheel display behavior adjusted for "Static with Display" mode, sound mix refined, and iRacing setups updated.
Audi 90 GTO: turbo and blow-off valve sounds improved.

Physics

GTP entries received tire, setup, fuel-burn, weight, aero, and related vehicle-property changes depending on model.

Tracks

Autódromo Hermanos Rodríguez (Grand Prix): Track Rules tab updated; stadium section now gives a 1X for 4 wheels off at the center of the turns; pit wall visibility fixed; some surface decals updated. EV Circuit gained 150m, 100m, and 50m marker boards.
Daytona Road Course: outside of Turn 1 is now both a 1X and a gain-time penalty zone; Track Rules tab updated.
Lånkebanen: UI now labels the Club layout with "Rallycross."

Telemetry and graphics

Telemetry: secondary incident limits were added to the session string as IncidentWarningInitialLimit and IncidentWarningSubsequentLimit.
Graphics: metallic tire shader applied to GTP tires, and Musco lighting near pit road was updated for proper nighttime illumination at various NASCAR tracks.

For league ops, we should republish track-limit notes, verify any telemetry tools parsing incident warnings, and retest GTP race runs with the updated tires and default setups.
