Watching a whole race on a weekend and cheering for your favorite team is different from locking in and completing it on a console screen. This is because attaining an impressive lap-to-lap performance on a full course is easier said than done. As a result, many NASCAR 25 players prefer 25% races that not only end faster but also maintain the authenticity of the sport.
Being one of the finest works of iRacing Studios, the game delivers an immersive experience that simulates the sport to near perfection. However, this simulation can be compromised, especially when a race is shorter than usual. To ensure you maintain a realistic race, even at a quarter length, here are the best NASCAR 25 settings you need.
All Settings For Maintaining Realism

To achieve a truly lifelike experience at shorter race lengths, head to the settings menu and consider the following tweaks.
Career Settings
Here’s how your career mode settings should look:
- Damage: Full Damage
- Race Length: 25%
- Tire Wear/Fuel Consumption: 4x
- Player Tire Wear: More Wear
- Player Tire Grip Fall Off: Less Grip
- Yellow Flags: Relaxed
- Black Flags: On
- Stages: Multiple Race Stages
- Qualify Setting: Quick Qualify
You have full damage because even if a race is shorter, the car should behave realistically in collisions. Tire wear is four times more than usual, so you still get to replace them at just a quarter of the race length.
The grip fall off prioritizes less grip, making it harder for you to carry worn-out tires and pit ASAP. This way, you’ll be forced to visit your crew at least once throughout the event.
Similarly, yellow flags are relaxed so that they can interfere with the race, but not for an extended period. Black flags are enabled for the sake of authenticity; however, you can turn them off if you want to speed up in the pit lane.
Driving Settings
Since driving aids are personal preferences, adjust them to your liking and make the following changes to the Draft Effects:
- Super Speedways: 10
- Other Tracks: 10
AI Settings
These tweaks determine the behavior of the opponents you’ll come across. By making the following changes, they can maintain a realistic nature:
- AI Difficulty: 100
- Skill Range: 25
- Stability: 50
- Recovery Skill: 10
- Consistency: 50
- Incident Frequency: 10
- Tire Wear Effect: 30
- Fuel Consumption: 50
- Impact Forces: 100
- AI Cars in Practice: 20
AI Difficulty is set to 100 with 25 Skill Range, 50 Stability, 50 Consistency and 100 Impact Forces to keep opponents challenging yet realistic. To simulate real-life drivers on track, the Incident Frequency value is maintained at 10 because mistakes aren’t common in an average race. You have 50 Fuel Consumption and 30 Tire Wear, so the teams you are up against also get to visit the pit lane, maintaining a fair yet authentic experience.
With these, you can expect the most authentic NASCAR action even at 25% of the length. However, consider also opting for the best NASCAR 25 controller settings to maintain the highest level of realism.
