Looking for some suggestions here. Cars don’t feel like they’re reacting the way they did in FM7.
Unique to AWD for me. Cars are glued in high-speed cornering and deceleration through tight corners.
But once on the gas accelerating out of tight low-speed corners, I’m getting a slight push I’d like to correct.
I’m not sure I fully understand the tuning of the front and rear differentials in the AWD platform.
Is this where I should be hunting up my problem or do you think it’s somewhere else.

What kind of push? Oversteer or Understeer?
Also how would you best describe the push? Juddery? Sudden? Slippery? Smooth but unexpected?
The more descriptive you can be the better. It’s tough to give generic advice about issues a car might be facing, especially without a look at your current settings, but the more descriptive you can be, the more likely the help you get will be correct. Be as verbose as possible.
Understeer. Smooth, it’s manageable. Would just like it gone. Is just slight understeer that requires a let off on the gas to correct. Only happens in my AWD builds. It’s pretty minor. Just being picky.
There are a few possibilities that come to mind. It’s possible your rear diff is locking which with grip can make the car understeer. To test this you can remove locking from the rear to see if there’s any change. If it removes the understeer I would add the locking back in and adjust bias more to the front. Then if you still have the push start reducing the rear locking.
It could be too much front locking too. I think this is less common for people to choose to do. If
Seems like the offroad diffs default to 100% locked front and rear, accel and decel. I’m guessing this is not the case with your tune. If it is I always drop the values.
Do you want to share what class you’re tuning and existing diff settings?
Yeah based on the symptoms, I’d agree that you’re acceleration diffs could be too high. Calling it smooth could also mean center diff. Front and rear diff being too high causes more of a wall feeling, like the car refusing to turn more when you know it can. The power of the car could be too far forward, causing it to act more like a FWD when accelerating out of corners.
Could also be antiroll or front end grip.
Anti-roll usually feels very sudden, almost like the car is jerking you straight, but it can feel smooth in cars that are very low and wide like hypercars. Both front and rear anti-roll being too tight can cause on power understeer, as can the difference between them.
Front end grip can also be smooth, though most of the time it’s accompanied by noise and/or front end histrionics. There are four possible sub-options for solving this.
-
Increase front end downforce (ideally through aero): As you accelerate any car, weight transfers towards the back, making the front end effectively lighter and removing downforce on your front wheels. This loses front end grip and causes on power understeer. Either adding downforce to the front or removing downforce from the rear is the only way to solve this.
-
Front tires over or under inflated: Over inflated tires will feel “skippy”, while under-inflated tires will feel “slidy”.
-
Not enough camber for the car’s power: Camber increases a tires lateral grip at the cost of straight line grip. As you add more power to the car, the front has more need for lateral grip to handle said power, as that’s what’s used to turn the car. Increasing caster can also add lateral grip without losing straight line grip, but too much caster can cause an excitable front end and caster wobble at high speeds.
-
Front tires aren’t thick enough: Sometimes the only way to get the lateral grip you need is to add more surface area. It is possible for a tire to be too thick and add understeer back in, but I wouldn’t worry too much about it in this game.
Probably too much of an information dump. You’re first stop is definitely differentials. You can come back and re-read the post if that doesn’t solve the issue.

Pushing on corner exit indicates two things.
Weight transfer is happening too fast and your pulling grip from your front.
Or
Your differentials are locking too fast.
Try these, in this order.
Lower front and rear diff accel
Move your power split to the rear
add front rebound
Add rear bump
Add rear spring
Lower front ride height if it isn’t too low already.
The posts above talk about front tire size and downforce. These are more noticeable on initial turn in and mid corner. They are less likely to cause understeer on corner exit. Corner exit issues are almost always weight transfer issues, or differential issues.
You try to power out of a turn the weight transfers to the rear of the car. If that happens too fast you over power the tire and get oversteer if the car makes enough power, if the car does not make more power than the tires can overcome you get understeer. To fix it you have to hit the rear tires harder for understeer or softer for oversteer.

there’s a lot of good information in this thread, but it seems way too complicated for your problem. you can probably fix understeer during acceleration by increasing rear bump a couple of clicks, or decreasing front bump. go softer for offroad, stiffer for road
I would increase front accell not decrease.
IE move slider to the right.
i wouldn’t worry about differential settings. you could set every AWD car in the game to…
0
50
100
50
50
…and you’d be fine. i wouldn’t do it, but you’d be fine for pretty much all terrains. damping is the most important tuning setting to master, especially when discussing understeer/oversteer during acceleration/deceleration
Another way to set it: Front 55/0, Rear 55-65/50, F/R ca80, depending on how much oversteer you want.
