iRacing 2025 Season 3 Patch 2: race control, car systems, and track polish updates

We’ve got a small but important iRacing patch here, focused on simulation fixes, car system updates, force-feedback tuning, and track-side cleanup. The official notes are in the release announcement.

What changed

Fixes

Reconnect behavior was fixed so drivers should no longer become invisible after disconnecting and reconnecting.
Race restarts were fixed to prevent sessions from getting stuck on One-To-Green.
Wet grass and gravel tire interaction was fixed, including an issue that could make formula cars snap and spin too easily on wet gravel at full throttle.
3D curb popping was reduced, and many grass textures were updated.
Force-feedback updates softened rumble-strip output in the 360Hz channel and rebalanced Wheel LFE defaults, including lower Moza master volume, higher Fanatec master volume, a lower default road-texture gain, and removal of the drive shaft effect from app.ini.

Cars

NASCAR Cup Series Gen 7: vehicle systems can now be shut off while over pace speed.
NASCAR Gen 4 Series: superspeedway gauge/light behavior was updated, and iRacing setups were updated.
Supercars Gen 3: anti-roll bar blade positions are now adjustable during pit service, with 25 seconds for one blade change or 50 seconds for both.
BMW M Hybrid V8, Cadillac V-Series.R GTP, Porsche 963 GTP: Brake Migration and Brake Bias Target can now be mapped to in-car controls.
BMW M4 G82 GT4: exterior lights were adjusted for daytime rain.
Dallara IR18, Ferrari 296 Challenge, Gen 4 Ford Taurus - 2003, and Porsche 911 RSR each received targeted fixes or display adjustments.

Tracks

Bristol and Darlington received lightmap improvements.
EchoPark Speedway (Atlanta), Lucas Oil Indianapolis Raceway Park, Michigan, Phoenix, and The Bend received environmental or visual corrections.
Bristol also gained an illuminated front-grandstand sign.

We should update league driver notes for restart procedures and wheel LFE changes, and account for the new Supercars Gen 3 pit adjustment timing before the next event.

[h2] 2025 Season 3 Patch 2 Release Notes \[2025.06.21.01] [/h2]

fixes

This Patch Release contains updates and fixes for the 2025 Season 3 Release.
[h2] SIMULATION: [/h2] --------------------------------------------------------------
[h3] Connectivity [/h3] [*] Fixed an issue where users could become invisible to others in the SIM after disconnecting and reconnecting. [/*]
[h3] Race Control [/h3] [*] Fixed an issue where Race Restarts could get stuck on One-To-Green. [/*]
[h3] Dallara IR18 [/h3] [*] Fixed an issue where the wheel vinyl toggle wasn't working correctly. [/*][*] Updated the position of the nametag on the no-post version of the Oval aeroscreen. [/*]
[h3] Ferrari 296 Challenge [/h3] [*] Increased the clutch inertia to resolve an issue where when using auto-shift on the 6th to 7th gearshift, the clutch would become numerically unstable and explode the drivetrain. [/*]
[h3] Gen 4 Ford Taurus - 2003 [/h3] [*] Adjusted the graphical display of left and right side fenders to better match those of the Chevrolet. [/*]
[h3] Porsche 911 RSR [/h3] [*] Fixed an issue where the pit limiter and warning screens wouldn't illuminate properly on the digital dashboard. [/*]

cars

[h3] Physics [/h3] [*] Fixed an issue with how tires play with wet grass and gravel friction. [*] This was also causing formula cars to snap and spin easily on wet gravel while at full-throttle. [/*] [/*]
[h2] CARS: [/h2] --------------------------------------------------------------
[h3] NASCAR Cup Series Gen 7 [/h3] [*] Fixed an issue where the vehicle systems could not be shut-off while over pace speed. [/*]
[h3] NASCAR Gen 4 Series [/h3] [*] These cars now use the low oil pressure light and the oil and water temperature gauges when at Superspeedway tracks. [/*][*] iRacing setups have been updated. [/*]
[h3] Supercars - Gen 3 [/h3] [*] Anti-roll bar blade positions are now pit service adjustable. [*] ARB blade changes are performed simultaneously with the rest of pit service and take 25 seconds for one ARB blade change or 50 seconds to change both ARB blade positions during a pitstop. [/*] [/*]
[h3] BMW M4 G82 GT4 [/h3] [*] Adjusted the exterior car lights to illuminate properly during day-time rains. [/*]
[h3] BMW M Hybrid V8 [/h3] [*] Adjustments to Brake Migration and Brake Bias Target may now be mapped to controls while in-car. [/*]
[h3] Cadillac V-Series.R GTP [/h3] [*] Adjustments to Brake Migration and Brake Bias Target may now be mapped to controls while in-car. [/*]
[h3] Porsche 963 GTP [/h3] [*] Adjustments to Brake Migration and Brake Bias Target may now be mapped to controls while in-car. [/*]

tracks

[h3] Graphics [/h3] [*] Reduced the amount of visual popping that could be seen on many 3D curbs as a camera changed distances from them. [/*][*] Many track grass textures have been updated to fix some splotchy patches and crab grass. [/*]
[h2] TRACKS: [/h2] --------------------------------------------------------------
[h3] Bristol Motor Speedway [/h3] [*] Placed an illuminated sign on the front grandstand. [/*][*] Lightmaps have been updated and improved. [/*]
[h3] Darlington Raceway [/h3] [*] Lightmaps have been updated and improved. [/*]
[h3] EchoPark Speedway (Atlanta) [/h3] [*] Tucked the terrain in behind the SAFER barrier at Turn 1 and Turn 2. [/*]
[h3] Lucas Oil Indianapolis Raceway Park [/h3] [*] An improperly pitched tent has been removed. Its owner has been enrolled in remedial tent pitching classes for the next two weeks. [/*][*] Removed some ads around the dragstrip. [/*]
[h3] Michigan International Speedway [/h3] [*] A levitating RV has mysteriously vanished. [/*]
[h3] Phoenix Raceway [/h3] [*] The weekend haulers have been better positioned. [/*]
[h3] Shell V-Power Motorsport Park at The Bend [/h3] [*] Some floating brake markers have been properly attached to fixtures. [/*]

physics

[h3] Controls [/h3] [*] For force feedback, softened the profile of rumble strips in an effort to reduce the audible noise they produce in the 360Hz force feedback channel. [/*][*] LFE system improvements for force feedback have been added, including: [*] Moza wheels now have their master volume set -15 dB lower. [/*][*] Fanatec wheels now have their master volume set +5 dB higher. [/*][*] Road texture effect now has its default gain set to -30 dB. [/*][*] Drive shaft effect has been turned off and removed from the app.ini file. [/*][*] These changes should rebalance the mix for Moza wheel users, greatly reducing the audible noise the wheel produces when the Wheel LFE system is enabled. If you still find it is too loud, you can further reduce the volume in the Misc. tab of the Sim options, using the master volume slider in the Wheel LFE settings. [/*] [/*]
