What is Understeer?
Understeer is when, at times, you find yourself on the corner trying to make a turn, but unfortunately, the car does not turn as you would have wished because of the lack of front grip to engineer the turn.
That is very frustrating since it implies that either you are going to have a to turn so slowly or to take the outside of the corner so as to be able all the same to make it.
Therefore the only thing that the driver is left to imagine here is running over all the apex kerbs while they are still driving and also employing more of a v shape on the centerline in order to minimize the amount of tie lost coming out of the corner.
Naturally, most of the beginner drivers tend to opt for a little understeer preference during their turns as that makes the car more comfortable.
What is Oversteer?
To put it very simply, this is where the rear end of a car steps out more than you would prefer it to. This is usually the result of losing the rear traction, and as a result the back end ‘steps out’ and has to be caught.
The steering dynamics in most cars are such that this rear grip loss is induced by turning in too much. In simpler terms, the steering grip in relations to the tires will simply not permit the car to go this way.
This, you will have to say, let go of the throttle and or if you try to wheel it back using the uncoordinated movement of the vehicle to avoid getting stuck in the gravel.
How To Fix Understeer in ACC?
If you are afflicted with understeer, it is possible to remedy the situation.
Tyre pressures
- Reduce front tyre pressure: This will increase the contact patch and therefore the front grip. It will also consequentially reduce the front rid eheight, so more of the front mechanical grip is deployed.
- Increase rear tyre pressure: This will increase the contact patch and therefore the rear grip.
Anti-roll bars
- Decrease front anti-roll bar stiffness: It means that the car will be able to shift the mass to the front in less time meaning that the front grip will increase.
- Alter rear anti-roll bar stiffness to a stiffer value: this will make the rear slighlty loser, therfore generating more rotation from the car at the apex.
Toe
- Put more front toe: This will make the car want more spin at the apex.
- Remove Rear Toe: This will make the rear of the vehicle more rotatable rather than the front.
Ride Heights
- Lower front ride height: This will allow the car to shift weight to the front faster and thus create more front in the corners.
- Lower rear ride height: This will enable the car to shift speeds toward the rear more rapidly hence will lower grip in the rear.
Cambers
- Add front cambers: This will make for a more pointy car at the front cut, more evident in medium to fast cornering.
- Lower rear cambers: Car will spin more with rear wheels having lower contacts due to lesser critical angles on the medium turning radius.
Aerodynamics
- Lower rear wing: This enhanced steer response also comprises a decrement weight which couples with other internal forces thereby decreasing drag with less rearward airflow onto the surface of the wing.
Of course, there are lots of measures you can apply in order to rectify understeer. But how do you know which one to use?
It varies depending on the circumstances and car handling. For instance, if you find yourself getting stuck in slow speed corners, a possible solution could be to increase the front toe or decrease the rear toe.
If on the other hand, exit understeer is what is causing you trouble, then you can either increase the rear anti-roll bar stiffness or decrease the front anti-roll bar stiffness.
How To Fix Oversteer in ACC?
If you have ever been in a situation where oversteer is a constant threat, the following are steps you may follow:
Tyre pressures
- Front tyre pressure increase: This will reduce the contact patch and in this case reduce front grip. As a result, it will also elevate the front ride height resulting into less support on the front.
- Rear tyre pressure decrease: This will also increase the contact area thus improving rear grip.
Anti-roll bars
- Increase front anti-roll bar stiffness: This makes the car transfer the weight to the front quicker therefore reducing front grip on cornering.
- Decrease rear anti-roll bar stiffness: this will soften the rear slightly therefore reducing the amount of car rotation at the apex.
Toe
- Decrease front toe: this will tame the rotation tendency in the front end of the car.
- Increase Rear Toe: This will help reduce the tendency for the car to slide at the rear.
Ride Heights
- Increase front ride height: This will create less front load when braking hence contributing greatly to less oversteer.
- Decrease rear ride height: This will lower the rear end of the car leading to better control of the back end of the car for the driver.
Cambers
- Decrease front cambers: As with camber changes on the rear, this will reduce understeer on the front, however, such changes are not ideal in medium to high-speed turns.
- Increase rear cambers: Adding higher rear cambers brings the rear end of the car in faster and allows the car to hold tighter lines increasing rear grip reducing the chances of exiting with oversteering especially in the medium speedy corners.
Aerodynamics
- Increase rear wing: Adding a bigger rear wing will help enhance the rear aero grip reducing oversteering. The only problem is if it aiuses too much deceleration during Tanya flight.
Well, there are many ways how one can overcome oversteer. But, how do you choose which one to use?
That depends on your oversteer severity and the overall car settings. If you tend to suffer an entry oversteer, to reduce this effect you may want to raise the front anti roll bar or cut down the stiffness on the rear anti roll bar.
When you are experiencing exit oversteer, this could be the time to soften the rear end of the car a little and consider softening the caster as well.
General tips
So here were the main solutions to fix understeer and oversteer in understeer and oversteering in Assetto Corsa Competizione.
Having said that, there are a few general tips that can help you with your car set up preparation:
1. Always start with the basics
whenever you are setting up a car, it is only fair to start from the basics.
which in thumb rule is making sure that your tyre pressures are correct, your ride height is correct and your camber is correct.
After you have done the correct the 8 fundamentals, you can embark on the latter settings which you will be attempting to enhance the car performance.
2. Don’t make too many changes at once
The rule of the game is that do not change more than one thing at a go when preparing your car for the preferred settings or configurations.
Too many drastic alterations might make you redundant and render all your good efforts useless!
3. Always test your changes
After changing any of the car’s set-up parameters, you have to try it out to see if it had an effect on how the car behaves.
In this manner, you will be able to identify whether or not the alteration was beneficial.
4. Keep a log of your changes
It is also useful to record all of every adjustment you perform to your car.
That way, you will know or remember some good things that have happened and some mistakes that could be improved
5. Get help from PRO drivers
Get or line up with pro drivers to get some attention if you seem overwhelmed about getting your car’s setup fixed.
By trying such things you ought to learn from their experience and more hope you’ll be able to find a reasonable setup that is proper for you.
Therefore, that is how you can modify the understeer and oversteer in Assetto Corsa Competizione. If you would wish to share any other suggestions, feel free to do so! 🙂
