Learn To Control Understeer and Oversteer - The Secret of Sim Racing Success
HTML-код
- Опубликовано: 26 сен 2024
- One of the most valuable things you can do to get better at sim racing is to understand the very thing you're using to do it - your car! Understeer and Oversteer loom over everything you do - every single lap, car, corner and maneuver is done at risk of these two things. Know your car and out-drive your competition.

Your humor is too powerful
Dope!
...Or as Richard Hammond says:
Understeer works like this, you turn the corner, but the car goes straight on, crashes into a tree and you die.
Oversteer works like this, you're driving along the same piece of road, but the back of the car comes round, crashes into a tree and you die.
Now, oversteer is best because you don't see the tree that kills you.
I feel like this is a topic I already know about but I clicked the video just incase there's something I don't know about. Love the videos.
Thanks man!
Your clarity and precision in explaining is delightful
Thanks so much! A comment like this is HIGHLY spreadable on my toast
Being a fan of Danny Lee is like being a fan of racing before cars were invented
P.s: love the educational content
🏆 FIRST award
Thanks Danny. Although I'm on PS5 & don't play iRacing, just ACC & GT7, your training videos have taught me so much. It's appreciated. Thanks again.
As a straight American male, I am very attracted to your voice.

In the words of the great Richard petty “understeer is whe the front of the car hits the wall, oversteer is when the back of the car hits the wall”
After watching two videos of your channel I have to say as a rookie simracer, there is no way around of subscribing to your channel 🤗🙂🙃. Such much love to detail in this video. Easy explaination with easy visualization. And no overwelming the viewer with hard cuts and too fast speaking or distracting music. BR Timo
Thanks, man - I really appreciate that 👍
This explains when I adjusted the curve on my brake pedal that suddenly I'm oversteering on every corner entry.
Sir you are like the house of wisdom for sim racing. Thx to you I am getting better and better and can learn from previous mistakes! Thank you so much, please keep up the good work!! 🙏👍👍
After watching this video I realized I manage my front and rear grip balance around corners way better in real life probably due to feeling the car better due to G’s and feeling the suspension and tire flex. In the sim,which is why I’m watching this video. I really struggle with grip management due to relying on wheel feel it throws me off a little.Side note (The more I’ve been doing research on how to get faster in sim racing makes me realize how much details sim racing will never be able to simulate in real driving,but I also think this is why a lot of pro sim racers are majority doing really good in real racing bc they’re used to controlling the car with less details and using knowledge and wheel feeling and ofc hearing as well and vision)
Your explanation was excellent; I now have a much better understanding of bias systems. I will definitely apply what I’ve learned. Thank you for the great video
This is like the Bill Nye the science guy stuff for sim driving tips. This is golden material and can be easily digested by all levels of sim drivers.
Brilliant stuff Danny! Another great informative video! I’ll be sending many people here as reference! I think it’s the best breakdown of this concept that I’ve seen and the best examples provided imaginable! The work and effort put into this video did not go unappreciated! Even though I already knew everything you talked about it was a great watch anyway. Only thing is in the beginning when you mentioned that bad driving is not under/oversteer “it’s you”. It is still understeer and oversteer even if it’s to an extreme degree. Still a brilliant video and I think the best on RUclips! Thanks for your hard work Danny!
Thanks so much for the comment, I appreciate it! This stuff is all for my viewers so it makes it worthwhile to hear it
Way more interesting and detailed than I expected on this topic. Thank you!
Thanks! Appreciate you stopping to comment ✨
Your videos are always great Danny, well done and very informative for the up and coming racers out there.
Thanks man - it's been a long time coming since the last guide. Never again will there be such a big gap!
@@dannyleeracing quality over quantity any day 👌
I developed an instinct to balance the weight of the car in sim racing before learning the theory. Thanks for the video. Now I know that I'm doing it right.
Oversteer: Steering too aggressively can also upset the balance of the car, causing oversteer (especially in a car like the Porsche 991 GT3 R), where the rear tires lose grip and the back of the car slides out.
Understeer: If you're steering too much, the car can start to understeer, meaning the front tires lose grip, and the car won't turn as effectively. This happens because you're asking the tires to turn more than they can handle at speed.
ersteer happens when the rear tires lose grip, causing the rear of the car to slide out more than you intend during a corner. This can lead to the car spinning out if not corrected.
Oversteer is typically caused by:
Too much throttle while turning.
Too much steering input or sudden steering changes.
Lifting off the throttle suddenly, which shifts weight forward and lightens the rear.
Correcting Oversteer: You can counter oversteer by gently steering into the slide (also called counter-steering) and adjusting the throttle to regain grip.
In a car like the Porsche 991 GT3 R, oversteer is more common due to the rear weight distribution, and controlling it becomes a key skill.
There's something about learning and then applying it to something you love doing.
It feels like something you 100% will appreciate when it makes your passion and craft more understandable
Good video. On the other hand, I do have the Trubrake mod and Axcsim mod for the gas pedal for logitech pedals. They are great. No paid ad, just a satisfied customer. 😅
Ever since i got into racing games i never understood exactly what is the reason why i spin out. This video helped me understand thank you so much
Thanks man, glad it helped - keep going and keep learning
You should've mentioned the differential. It tends to lock up under full throttle, producing understeer
You said in the video that you were not a set up guru lol but the way you simplified the concepts in the video was very helpful, great video!
So I play Forza Motorsport because of its blind driving assists. I struggle to drive rear wheel drive cars, and I finally understand why. I always chalked it up to traction loss, which I guess it was, but from what this video implies, I'm using too much throttle, causing the back end to lose grip. Front wheel and all wheel drive cars though, drive really well for me.
4:20 i dont think ive ever even thought of the tires in this way
3:14 this graphic is very helpful
Great guide!
I'd like to say that AXC Sim is absolutely legit! I bough the TrueBreak mod as well as new potentiometers a year ago and they completely changed my pedals for the better, they're easy to install too!!
i keep having oveersteer moments on acceleration with the amg evo in slow corners . so thankyou that nhelped me loads
Thanks for watching and letting me know - You're not alone with that, the AMG struggles for rear grip in slow corners because of the front-engined layout, but you benefit with front end poise and stability in the higher speed stuff, so it's a trade-off with that layout of car.
@@dannyleeracing honestly that helped me loads i was stiffning front ujp instead of back now works a treat honestly thankyou bro
Great video. Very informative 👍
This information could help me in real life. When I crashed with my car that just had new front wheels. Causing it to oversteer and it was very very scary. Luckily nobody died. But I was effected and I still feel my neck after 5 years after the accident. 😢
DANNY LEE! Thank you I needed this
just over 6 mins in and i already know the point of this video. no need fit the rest. Im omw to find out if i prefer salt or pepper with my electrucity🤣.. Good videos.
This video was just about oversteer and understeer but the bit at the end about setups just opened up a whole load of understanding about it.
That was a such a small portion of the video, but that opened up so much for me.
I have a local GR86 cup in my country next week and I'm definitely using this information to figure out how to set up my car. It's only my second race ever since I got my MOZA R5 and setup was always a mystery to me.
Awesome video. Too bad i can't give you a new subscription since I've already subscribed about 2 years ago 🤣
Just started sim racing so obviously started with forza horizon😂😂. Just getting to grips with my g923 and seat. This video has been amazing for my confidence
Thanks man - you're making the right moves!
At 0:10 and 1:30ish, you park that car on the apex. Nice control 😀
The separation of rotation to the front and stability to the rear is a good intermediate explanation, but it has flaws. Rotation comes from a torque applied to something. In a car, this torque comes from the force of each tire times its leaver to the center of mass. This gets quite obvious if you play with trail braking and let the rear step out under braking. You can get the same rotation or spin by adding more angles to the tires with the steering wheel or getting harder on the brakes. You can also understeer while braking if you load the front tire too much. That happens when the front axle toes in under load and how road cars balance tire life vs safety.
Speaking of the main parameter for stability besides load is the toe. The more toe you have the more stability you get from that axle, but you lose rotation. That's quite obvious for the rear axle. With more toe the rear tires are facing more towards the center of the car. So the longitudinal forces of the tire get a smaller lever to rotate the car. On the front, it`s more difficult. The outside tire of the corner gets a better leaver, but the inside tire gets worse. Unless you fully unload the inside tire that also gives stability at the cost of rotation. That's what makes the highspeed corners in Spa or at the Nürburgring Nordschleife so tricky. At Schwedenkreuz Nordschleife you completely unload the inside front tire so you need a loaded rear to make the corner. At Radillion Spa you unload the left side, into a huge compression as well as load the left, and then unload the left again. This variation of stability makes the corner really tricky and you need to have a precise line through it.
If you want to play around with this try harder or softer springs with lower or higher ride height. So the effective ride height stays about the same. A softer axle will toe in more when you load it, and a harder axle will toe in less. In conjunction with your driving style that's how you tackle over or understeer in specific parts of the corner. With a stable car, you can use more trail braking and start getting on the throttle earlier. With a more pointy car, you need to stay straighter while braking or accelerating and coast mid-corner for longer. Both styles can max out a tire's grip but they require different lines and techniques.
I wish I could like this multiple times.
Thanks so much, man!
Very helpful, thanks.
I’m glade I found this channel. I’m able to think about different things now when I’m racing. Thanks Danny 👍🏽
Love your content. The way you explain everything is great 😊
Thanks, man - happy to hear it and cheers for the kind comment
Nice advices! Thanks from Uruguay 🇺🇾
Brilliant explanation - thank you!
Thanks man, hope it helps you move on forward!
thank you alot, this was my issue
Fantastic vid bro
Now I understand, but I’m anxious about how much I know
I play GT7 and ACC on the PS5 but much of what you said can very well be used. Thanks for the great video!
Thank you for excellent content that helps us :)
Wow, Logitech brake upgrade. Thanks my dude, affiliate link it is. 3rd video in and I've clicked to subscribe.
Envisioning a back bumper livery saying Logitech G29 as I pass a $1k Fanatec user!!!
Thanks man, I hope you enjoyed these videos and those that are to come. The truebrake is peak Logitech braking, check my 2023 review on it in case you wanted to know what spring setup I used.
it's all about rear and front high.. oversteer? rear higher. understeer? front lower.
Rear wing? More straights = less wing
More corners = more wing
SPA MONZA wing at 1 etc..
And than you set up front and rear high to the point that you can survive the race.
Wow man, superb explanation! What I really liked best was your usage of the camera angles and such - outstanding! I try to use it as much as possible for my own videos and I definitely learned a few more things about it now. By the way, if you wanna shrink the iracing watermark, just hit ctrl+pgdwn or up in order to de- or increase the ui size while recording.
Wonderful and informative video Danny, muchos apprecianos!!
Cheers, man!
my favourite setup change for reducing oversteer is limiting the front suspension travel - stopping the nose from pointing at the floor too much. Without having to stiffen up the front springs or decreasing rear wing. It frustrates me if some games don't let me limit suspension travel.
Limiting front suspension travel how? Like changing where the bump stop is? Higher spring rates? Lower ride height?
@@alecmillea4539 bump stop range of course. Narrow it down and your car will lean on that instead of diving.
@@catnipherb In real life if your car is hitting the bump stops under braking it’s set up wrong. It means there is no suspension movement left to absorb bumps in the braking zone and the car will be extremely unstable. It might work in whatever game you use it in but in real life that would kill you. Hence why it’s not an option in most games. Effectively you have no suspension on the front end while braking. If the track is glass smooth it’ll be fine but the second you hit a bump you’d die.
@@alecmillea4539 I don't know. I use fast bump and fast rebounds to deal with curbs and uneven surfaces. Pick any track and any car, go into their aggressive setups and you'll bound to find some cars will have short bump stop ranges by default. I'm sure Aris sets them like that for a reason.
fantastic video... great job.
Great video, felt like it was a paid lesson it was that good, just had to subscribe, felt it was only fair for the content provided. Cant wait to go through your other guides!
Thanks for the sub! Appreciated
Love the visuals
@danny lee
Great video.
Can you do a video about spring settings like dampening, ride height and rebound?
Can you make a video of how to use the clutch to take corners better?
Hi Danny do you have a video on traction control and how to adjust didnt see one, could be interesting if not :-)
Not yet, the to-do list is as long as the Spa Endurance Pit Lane
bottomline, keep your car stable and fast
This changes everything
🏆
I didn't understand anything until the baby analogy then it all made sense
Hahaha! Perfect
Dude thank you for giving us your time :) cheers
And thank you for watching!
Amazing video. Can you explain what people means que they say driving with the pedals?, whats the limit? How this work with tyre usage? Etc. i appreciate finding this channel. Keep it up
This video really helps, but can you trailbrake with a front wheel drive car or are you better to slow down before the corner and accelerate through
Very informative
Yes it has thank you for sharing that knowledge with me
First, this video was exceptionally efficient and explaining what exactly over/steer is. You really have a way with words when it comes to teaching.
Second, I have the Logitech wheel and pedal set and I bought the true brake mod a while back and it was a game changer. It makes my brake feel so good and realistic that I’m not all worried about upgrading my petals anytime soon. Admittedly the wheel leaves a lot to be desired but the pedals are fine.
Thanks so much for the mega kind feedback!
It's been 84 years- I mean 8 months since the last tutorial. You have this certain philosophical approach (I can't put a finger on it) with your explanations that it unlocks other perspective of answers to the same problem.
Dude, I feel it - I'll be pumpin' out one a month, soon
In motorcycle's term we call it lowside or highside..
Lol nice ref with Mitchell and Webb
I raced a car that looked like the one you use was that you last night ? Or morning bc I’m in America
Another cracking video mate. Your teachings are brilliant. I look forward to not being able to apply them due to my own impatience, but the main thing is, i know what you mean. 👌🏼🇦🇺
Thanks mate, appreciate the continued viewership and hope to have them along more often from now on...
You forgot tire pressure, camber and suspension setups, they also have effect on over and understeer.
Even a full or almost empty fuel tank is something that you can feel….
Man so many choices….
😂
So many - and that's what makes this stuff so absorbing for so long! But I guess it's best people focus on getting beans on toast right, before attempting a beef wellington. Plus my setup knowledge stops pretty much where the video does and I don't want to fall on the wrong side of 'confidently wrong'
Bop Bop Bop Bop, Bo-Bop! @2:42
All I have to say is wow very informative great video
Thanks, mate!
I have maybe a misunderstanding of the part coming at 7:18.
You say that as we are under braking, the front of the car has more grip, and the rear less.
Then, if we turn to brutally the steering wheel, then, the rear of the car having too low weight, then less grip, turning too much and too fast the steering wheel will lead us to ask too much to the rear wheels, that would not be able to keep the grip asked, and will lead to.... oversteering.
But on another hand, there is another understanding of it that leads me to a paradox.
If you turn more the steering wheel, you are using more of the front wheels grip potential to turn, and you are leaving less grip potential into braking.
Then, by steering more, you brake less, and by braking less, the rear of the car regains weight and the front loses it... this gain of weight into the front and lose into the rear would lead into understeering. Or you'll either keep braking as much but get into ABS and... understeer.
So regarding this conception, steering more = braking less = less weight transfer = understeering... the opposite of the previous conception, which also intuitivly makes sense to me.
I learned that from Suellio Almeida on this video : ruclips.net/video/dVfCvMcdMxU/видео.html.
I would like to get your point of view about it please.
That´s an awesome video. Thanks a lot for that!
And this is an awesome comment - thanks a lot for THAT. Much appreciated 🍻
How about "good luck" balance, what does it mean?
Very informative. Earned a sub.
Cheers, man!
Love to know how to gauge the braking speed going into the corner. I kind of understand that hard brakes and then turn into the corner but I think I am missing out something, the car understeers and slides, while by watching others they are doing the same thing but they don’t slide.
Sounds like you might be carrying a little too much brake into the corner as you turn the wheel - doing too much braking whilst turning can overwhelm those front tyres and cause understeer. A video clip would be proper helpful!
How can i eliminate understeer under braking with my gr yaris? Sometimes it just wont turn. Its also hard to get it into brake-oversteer even when applying the handbrake when not fast enough. So often the rear weight just pushes over the front tires. I think it has to do with the awd system. I already raised the rear tire pressure and applied some toe out on the rear. Any ideas? I dont want to make it completely unstable on high speeds though.
In Iracing, why does it look like the track is moving and the car is just placed on top of it.
Why do your graphics look better than mine? I do full details all maxed, looks half as good oO
Excellent content
Hmm, maybe I missed it but there is nothing about how to catch it as in what to do with the steering wheel on top of what to do with the pedals.
Mostly just reaction time and learn the car and part of the track that it under/over steers
You had me until you said "iTs NoT ____, iTs You" and then i felt attacked. It can't be me IM THE BEST idc if i just got my first wheel 3 weeks ago.
This confidence and determination is what'll take you far
😂
very informative. subbed
Thanks for the sub!
Is there a reason why at 7:50 (fixing oversteer at corner entry) you only talk about steering less strongly and not about braking less hard? When you're coming in hot and your rear wheels start to slide at corner entry it's a tough situation to get out of and I wonder is it always better to steer wider or could it be sometimes better to release brakes? Either way it's really tough situation to stay on track. I also noticed at 11:50 you talk about oversteer again but now only mention throttle and brake and not about steering. Im curious why ? Thanks for the great explanation btw. Subscribed !
Great video Danny:)
Cheers Mike, hope it helps!
6:00 Is F1 cars not lawnmowers half of the time?
Sorry if you already answered this and you can call me dumb, but I don't understand the part about a rear drive car suffering from corner exit oversteer from too much power to the rear. Wouldn't more throttle help against oversteer instead of causing it since it's shifting weight to the back?
You recommend some soft controlled throttling to remedy oversteer in that case, but wouldn't more throttle equal an even more effective result?
How does shifting weight to the rear TOO MUCH cause oversteer, shouldnt it help grip the rear?
EDIT: Nevermind, I didn't consider basic physics lol. The rear wheels spinning faster reduces grip naturally, offsetting the grip gains from the weight transfer.
That's right - if you put too much power into those rear wheels, the power will 'rip' the tyres free from the tarmac and they'll spin. When tyres spin, they can't grip the track - like how when someone loses their grip on an icy slope, it's much harder for them to regain grip on the ice while they're skipping over it so fast, so they'll just slide and slide until they're going slow enough again.
That's why powerful cars take so much care to drive - to get the best grip out of corners you have to apply power smoothly, but it's easy to overdo it and spin the rear tyres.
Danny Lee I have some problem in forza motorsport 7, iam using the g920 logitech, and my car keeps oversteering! This never happens with the Japanese cars I used. Iam currently doing a muscle car race. Is there a upgrade or setting that can help me stabilize my car. I wonder if I can send u a live video so u can help me out.
Ye I agree he is good at demonstrating
great video
Instructions unclear, I cannot steer now
Awesome
awesome
So, where is dead body??
That was a bit complicated. My way of doing it back when i used to drift a Silvia S14 was, if the car rotated too much aka understeered, i would left foot brake to shift weight to the front tires to give them more grip while keeping my foot on the gas to keep the engine in the power band and the turbo spooled. If the car understeer at corner entry, force the car to rotate by either more gas to break the rear loose, ebrake, or clutch kick
Very good job explaining 👏
Thanks man!
Does your wheel and haptics play a part in detecting under/over steer?
The wheel, definitely - haptics, not really
