A third update has arrived with iRacing 2025 Season 3 Patch 3 released with changes including an adustment of how driver divisions have been separated out. Not every pays attention to their division championships, but the splits were changed for the start of Season 3 and apparently it didn’t have the desired effect. So now they’re being adjusted a bit more.
Most notable among the other changes are an issue with GTP brake migration only being applied at half of the stated value, and a balance of power update for the whole GT3 class. There’s also a higher penalty if you cut the Inner Loop at Watkins Glen.
It’s a relatively small update, coming in at 186MB for everything. But you don’t really want big changes mid season unless it’s solving a major problem.
iRacing 2025 Season 3 Patch 3 Release Notes:
iRACING:
Flags
- Fixed an issue where some Race Results would display a customer’s previously selected Flag instead of the Flag they had selected at the time of the event.
- Results preserve the flag participants were flying at the time of event entry as historic data.
- This was especially noticeable for customers attempting to use our recently added flags for the countries of the United Kingdom: England, Northern Ireland, Scotland, and Wales.
SIMULATION:
Licenses & Official Racing
- Adjusted the distribution of iRating and ttRating values that define Division separation for all Official Racing and License Classes for improved competition at all levels.
- We had tuned the division distribution slightly with the start of 2025 Season 3, and we missed the mark by a bit. This second adjustment should clean things up and improve Ranked participation.
- With the deployment of this Patch, all members will be redistributed into Divisions for all licenses classes, just as is done seasonally before Week 1. This redistribution will be completed based on drivers’ iRating, ttRating, and Rookie status as they were a few weeks ago when divisions were first established during the 2025 Season 3 season transition. Drivers are not being redistributed based on their current iRating, ttRating and Rookie status. All previous 2025 Season 3 records, stats, and results will follow their owners into their new Division.
Graphics
- Fixed an issue where some damp to wet tracks could have blocky patterns appear at dusk.
CARS:
<Car Class> GT3
- GT3 Car Class BoP has been tuned for improved realism.
- iRacing setups have been updated.
<Car Class> GTP
- Fixed an issue where brake migration was being applied at half of the stated value. The ramping reference location has also been adjusted.
- At 100% pedal input, the brake bias is equal to the basic brake bias setting.
- At 0% pedal input, the brake bias is equal to the basic brake bias setting plus the brake migration gain.
- Please note, to adjust existing setups the recommendation is to halve the current brake migration setting and increase brake bias forwards by 1-1.25%.
- iRacing setups have been updated.
<Car Class> NASCAR Gen 4 Series
- iRacing setups have been updated.
Acura ARX-06 GTP
- Brake Migration adjustment has been added to this car to bring it into line with the other GTP class cars.

- Note, brake migration was already working correctly in this car and thus no physics changes have been applied nor is it necessary to adjust setups for this car.
