If you want to go fast in racing games & sim racing, understanding what slip angle is and how it works is critical. Let me explain...
As your tyres reach the limit, they gradually relax their grip on the road and stretch. Due the elasticity of the rubber, the tyre has to deform to achieve maximum traction.
As your cornering speed increases, the tire contact patch ends up pointing in a slightly different direction than the wheel is actually facing. The angle between the direction the tire is pointing and patch the car is following is the slip angle.
The tires traction limit, and it’s cornering limit is achieved within an optimum slip angle range. Up until that range is reached, the tire is not generating its maximum traction. show graph These particular tyres are at peak traction when there is 6-10 degrees of slip angle.
Let's look at 4 different drivers and see how they utilise slip angle.
Our first driver has probably just started sim racing, and is a little inexperienced and conservative with his driving. He consistently drives with the tyres in the 2-5 dergee of slip angle range. As you can see from the graph, the tyres are not at their traction limit here. Driver 1 is not driving at the limit, and therefore, he will be slow.
Driver 2 has a bit more experience, and is known to be a little on the wild side. He consistently overdrives the car. But what does that mean? Well he always drives through the corners with a slip angle above 10 degrees. In other words, he’s sliding the car too much. Of course, it looks great on video, but the graph shows that in this traction range, the limit of the tyres has begun to decrease.
Our final two drivers are consistently cornering in the 6-10 degrees of slip range. Both are extremely fast. Both are cornering at about the same speed. Both are driving the car with the tires at the limit. SO, whats the difference? Driver 3 is cornering in the upper end of the 6-10 degree range, whereas driver 4 is around 6 or 7 degrees. Again, cornering speed is the same, but driver 3 is sliding a little more, causing ,more heat build up in the tires. Both drivers will run at the front of the pack early in a race, but driver 3’s tyres will eventually overheat and his speed will fade away.
Driver 3 is cornering with around 9 degrees of slip, whereas driver 4 is using around 6 degrees. Their cornering speed is almost identical. This tiny difference means driver 3’s tyres will gain more wear and tear throughout the race, and eventually overheat - making his speed fade away.
The goal is to drive the lowest possible slip angle that maintains maximum traction. However, the difference in speed between cornering with a slip angle of 2 degrees and 12 degrees may be just 1 or 2 miles per hour. It’s very subtle.
Fast drivers have developed a feel for how much slip they’re using, and using their tyre temperatures, they can adapt their driving style accordingly. There’s no secret to “using” slip angle, you just have to get experience under your belt and develop a 6th sense for it.

I absolutely adore how informative your videos are
miss you by Oliver tree but sped up

Me too. Thank you
miss you by Oliver tree but slowed down
I studied this when i was in college, the book i read had a section on slip angle but this is a way better explanation. I think i actually understand it now.
Fun fact, the plateau in maximum slip angle to grip ratio becomes a lot smaller the gripper the tire becomes. For example the graph bloke shows is what a slip angle of a street tire would look like, a long plateau with a smooth drop off in grip. If you were showing the graph for grip to slip angle on a racing slick, there would be a very narrow margin for peak grip before a very sudden drop off.
In other words manufacturers factored in how people would understeer on the streets
I love these instructional videos for aim racing, but I use them for irl driving and it really has helped me learn to control my car better from lift off in corners to initiate slides to the art of passing
This made me realize I was taking advantage of the 80s f1 tyres in AMS2 yesterday when I sent the worlds 4th fastest time on Brands Hatch GP. There was a certain point I was sideways but using all the traction of the rubber cause I outpaced the ghost in that specific corner. Cool video
Man bless you for being such a knowledgeable driver
Those short videos you make are a good to the longer ones, it's still informative and easy to watch
Back when i used to drive a camry this is exactly what would happen, at first i didnt control the slip, it would happen randomly as i did the turn but then i realized that if i just turned the wheel a little bit faster imbetween the start and the midle of the corner the car would slip towards the center of the turn and i could take the corner sideays, id do this going 70-80 in corner that were meant to go 40 in the mountains
Thanks a lot for the follow up video. This is a lot of help mostly because of the community I'm in. They think slip angle could just be *tuned* into the car
I mean, it kind of just exists
As long as you have rubber tires you cant tune it in or out, what they are talking about is probably rotation or yaw rate
You can increase it by, for example, toeing your rear end out.
@@tiagobelo4965 i tried to explain that but it goes no where
Wow. I remember studying such topics with books from Ross Bantley. And here we are 5-10 years later people make very fun and easy to understand videos on youtube for all of us. Great. Thank you!

How do you know when you’re in the right range? Also, with cars that aren’t balanced, so a front limited car for example, it will slide the front sooner than the rear. If you drive at the optimum range of the front tyres, the rears still have potential left. What handling do you use in this situation, or when it’s the opposite and the car is rear limited?
bring a protractor?
@@zwenkwiel816 💀💀💀 serious
you use trailbraking with understeering awds and fwds, or you can stiffen rear springs/sway bar or increase tire pressure at the rear
@@asdasd-om8tj but how do you know whether you’re in the range?
@@akioasakura3624 with experience you can find the feel for the optimal slip angle for the given corner, it varies track to track
mate, the amount of editing going into these videos is incredible!
That is insanely right and intuitively explained , sss tier simracing content. Something i have been dreaming of making, but on a larger scale with way more detail, for more experienced guys.
Yeah, that’s because he’s taken the wording and exact example from Ross Bentley’s book, Ultimate Speed Secrets, P33.
@@karlalliban thanks, might be a good read
me sitting in my sim rig with a protractor: *confused noises*
Goddamn; amazes me how well you transition your content.
it would be fun (not sure if helpful at all) an app to see on screen your tyre slip angle
Explain it once and for all❌
Do 2 videos of correcting✅
this is the last one haha
I really enjoy the information to duration ratio of this video. No faffing about whatsoever.
I know this sounds weird but try it on your local track with an old car you know your doing it right when your wheel is going from turned to strait throughout the corner. Its much easyer to feel in real life and you can bring that to the sim.
Buuut wear a helmet and dont use an suv more like the slightly sportyer family car.
I said nothing. You didnt hear this from me
man se que no sabes español pero que te quiero man buen trabajo
Why dont you have more subs and views? This channel is dope.
What about FWD Handbrake turns. When to use it, how to do them and such. Both Hairpins and Chicanes and 90° turns.
You want tires that allow lots of slip angle on FWD for rotation, Nankings, Falkens etc.
The most useful video I've ever seen
video on how to tune your car properly 4wd, fr, ff and mr
What would the perfect slip angle be in a gt3 car? And does psi have anything to do with optimal slip angle
Pretty good explanation
I’m going to learn today
what you using PPFilter? your graphic setting is masterpiece
more track videos we love them
I am using a GT86 and I can't seem to shift weight to the front long enough even if I'm completely off throttle. Can anybody help?
name of the song in the first 5 seconds of the video?
Great explanation!
The best way a game shows this is in beamNG Drive with cars which have tall and narrow tyres
this must be TSRB favourite topic, I just know it c:
I see people misusing the term slip angle everywhere now, because of my first video on it 💀 just trying to correct myself
@@TSRB honestly mate, you might be better off deleting the original and just making a new video with the corrected info
Helpful thanks!
What happens if I slams petrol pedal when slipping. I don't know how physical work, but I like to doing it.🤨
Great video
tour edition is awesome
What's the song that plays right at the start of the video?
miss you sped up
@@TSRB Thank you!
my problem is i have this feeling irl but not in games
That's okay, my problem is, i don't care i just drive
idk the feeling through the seat irl translates pretty well to force feedback in games for me. It's strange, they're the exact same sensations but through different parts of your body.
in games the feeling is similar to when you 're going into understeer, except it's not complete understeer, but rather very very small part of it.
@@TSRB I just find it difficult because I can feel all 4 wheels individually irl but to simulate that would cost enough money to buy a shitbox to terrorize the streets with. but I get what you mean I just don't think my Logitech g29 and wooden rig is gonna be enough. but I'll sure as hell keep trying
thx for the info
This man is giving maximum effort in every single video
what pp filter and weather script are you using?
Is PSI a critical factor here too?
That Evo 4 is so good looking! its the DDM one? or Sam´s?
ddm
@@FrosenHell yeh i noticed after commenting for the headlights! that car drives so good
Thx
Well done
bro had to call the emperor racing crew
very nice bro..
Speed secrets
How do you know the degrees in tyre deformation? I mean... is there a device to measure it or it is on the telemetry from the game?
Can I have your graphic settings?
Hey TSRB why don’t you try a car game call midnight racing tokyo on roblox also theres usb things to make your steering wheel work with pedals
ive tried it a few times in videos and on stream but its just not my kinda game unfortunately
@@TSRBoh I didn’t seen them can you show me you clips you did but that’s fine your such a skill driver but ok that’s fine
@@TSRB I saw a video of one
If you press m it change the gear shifting mode at st mt you are decent at the game for a beginner
Wait, how would you track your tyre temperature IRL?
sensor probes have been a thing for a good long while now
@@jn1211 and I haven't heard of them for a good long while until now
come in after a lap w a laser heat gauge and check the inner, middle and outside. this is also how you know where to adjust your camber but you MUST be running close to the limit of the car and tire beforehand
i drive like initial D with initial D music...
I use to own this car
jesus christ it took me a while to realize its sim footage and not real life
You sound like Kanata
*M Y L E G S H A V E S L I P A N G L E*
i think we can all agree driver 2 looked the coolest
i am definitely driver 2
intro music ?
miss you sped up
@@TSRB thanks bro
slip fart
🥴
OMG SLIP ANGKE IS THE BEST DRIVING THECHNIQUE EVER 1!1!!1!1!
now i understand why ryosuke lost
what
Ryosuke had them booty cheek tires
Nani
These fast pace videos with this song are terrible, please go bacc
thanks!!!
Damn I’m early
This is brilliant!!!! Subbed
As an ex-dev, I doubt those physics irl is simulated properly in sim games (but you can be right) Anyway, I’m just here to admire the EVO4. It’s hard to find a clean EVO4 irl nowadays…
I've heard they corrected slip angle from ac to acc because it was like too much slide in ac, idk how true is that
in sims with physical tire models such as rFactor2, LFS and BeamNG their simulation is 'correct' as close as the devs can get it. but AC and other tire models try to emulate as best they can. AC isnt a very good sim in todays standards, ive been simming for over 7 years and can say that with no hesitation.
@@julian10000 depends on the car/if its a mod. if you go to content manager ->content->*any car*->unpack data and look at the tire data you can see the amount of flex, optimal slip angle, heat/grip ratio etc. many mods are made by kids who havent sat in a car before and they end up feeling like toys that you can just throw into anything. the Kunos/Arch physics mods are some of the best there are out there in terms of irl. they may be a little bit exaggerated in terms of how easy they step out and rotate but if youve ever spun a car irl... youll know
@@SSmallwood my pc can't handle anything close to ac...
@@julian10000 dang, if you want to learn theory before doing sim racing i recommend driver61 and other actual race car driver and coaches to learn from. listening to TSRB is like listening to someone on top of mount stupid on the dunning kruger effect scale
If you want to go fast... dont drift.
PS: What software are you using to animate?
So speed sliding from track mania is real??
its extremely easy, just corner up to where the tires almost lose grip. thats it. when you get more consistent you can hit the lowest slip angle with maximum grip.
Your actually not doing it, you see slip angle is unintentional and comes if ur right at the limmit, it comes random but u can make it consistent
@@Viezyyy yes you said what i said but u added that it is random, dont you need slip angle to turn in the first place anyway?
@@reclaimer0018 slip angle is usually a foot away
u can acheave real slip angle by making a setup, or trail braking, etc
@@Viezyyy so by just taking the corner properly or tuning your setup…
Driver one has ONLY JUST STARTED SIM RACING and is already cornering with slip angle 💀
tires need slip angle to turn, it's not a special technique or anything.
Always good for a laugh (not for driving techniques though)
wdym this is the best driver i have seen
@@M4kkaraperunat yeah sure I'm pretty sure he could destroy Hamilton if he was gonna race him irl😂
Do game's even simulate this?
Simulators do
Delete all old vids relating to slip angle mate youve created a whole lot of audience who dont know what it actually is
Bro love the videos but just... Stop with these thumbnails. Please.
when they stop outperforming thumbnails without the cars edit i will
All these explanation Blah Blah doesn't matter if the player is using Keyboard.
Because with keyboard, it is either Full Steer or No Steer. It is either 1 or 0 no in-between.
sir this is a sim racing channel
This has not really fully explained how to actually do slip angle nor how to control it
try watching the video again
dude, slip angle cant be explained, its like riding a bike, you have to drive to learn it
just explained it
@@TSRB didnt understand one thing you said i am taking my vectra out to see if any of it is true and if i oversteer 5 degrees more than what you said i am disproving your video
@@mahuba2553 what i said in the video made 1000x more sense than that comment
