Grip Level

Front Grip and Response: The front tyres provide a more direct response during corners, enhancing the driving feel. But we need to be careful about car and tires combo. Hard tyres, while durable, present unique challenges in terms of control. They offer less grip compared to softer compounds, making it necessary to practise extreme caution while braking, acceleration, and cornering. The harder compound can be less forgiving, requiring drivers to adopt a smoother and more calculated approach to maintain balance.

Traction: Traction has improved, making acceleration out of corners more reliable. But again, this depends on the car and if the weight transfer is done in the right way.

Again, corner entry is now more important since that’s the part where we need to ensure that the car is stable. Making the car unstable on entry will cause problems on acceleration and even losing the back end.

Sliding and Tyre Wear

Sliding on corner entry, especially if turning the wheel too soon, increases front tyre wear. Rear tyres, however, are less affected by sliding. Even doing donuts won’t affect the rear tyres that much, while rapid change of direction can have a significant effect on the front tyres.

Recent changes in tyre performance dynamics indicate that tires lose more performance from sliding and turning than from braking and acceleration. This shift requires a strategic approach to cornering and overall tyre management as we have to focus more on:

Corner Entry Speed: Entering corners at an appropriate speed to prevent excessive sliding. Over-speeding into a corner increases the risk of sliding, thus accelerating tyre wear.

Smooth Transitions: Ensuring smooth transitions into and out of corners can help manage tyre wear. Abrupt changes in direction can increase tire wear and reduce tyre performance over the long run.

Controlled Steering Inputs: Using controlled and gradual steering inputs helps maintain the car's balance and minimises sideways movement, preserving tyre life.

Braking Bias

Impact of Adjustments: Changes to the braking bias now have a more noticeable effect on cars stability and adapting braking techniques for optimal performance is more important than before. I highly advise to keep most car on BB=0

Stability: Adjusting the braking bias can significantly influence the car's stability, making it more sensitive to precise adjustments. I do advise to try a couple of slower laps before deciding which brake bias you want to use in your hotlaps.

Force Feedback (FFB)

Enhanced Detail: The force feedback has been improved, providing more detailed information. However, the overall strength of the FFB has been lowered. I had to increase it by 60% with some cars. And this also meant changing my setting, which you can find in the link down in the description. I also made some changes in my suggested Fanatec settings article.

FFB issue: Most Fanatec wheels need to update to beta driver 457 to get better FFB. Although this is a beta driver that still has some bugs and may disconnect from time to time. This is a big disclaimer, so be careful with this change. You can find it here.

Driver 457

Assists

Assist hasn't changed much, but I noticed that TCS has a more significant impact on performance. I will advise not to use TCS if possible since it can lose even two tenths per corner. As usual, I advise to turn all other settings off, except counter steering assistance at weak.

Performance: Assists will result in slightly slower lap times. While the core mechanics of assists haven't changed, their effectiveness has been reduced due to the new physics model.

General Observations

Understeer and Oversteer: The new physics model demands a more controlled driving approach, balancing the increased understeer and oversteer.

Force Feedback Issues: Some players have experienced issues with force feedback, which can be resolved by updating to the latest beta firmware from the manufacturer.

Tyre Management: Tyre management has become more critical, with significant performance drops as tyres wear. Front tyre wear is particularly exposed when sliding into corners.

Lap Times and Car Behavior: Lap times and car behaviour have changed, with cars feeling heavier and requiring earlier braking. Sometimes even significantly earlier than usual.
