Formula 1 Anti-Dive Suspension Explained!

Or are we looking in the wrong place...
If you want even more F1 Data analysis deep dives...
www.buymeacoffee.com/brrrake/membership
Every race weekend I publish an in-depth qualifying and race analysis, breaking down all of the interesting strategies and technical stories that the TV missed.
Here are my thoughts of anti-dive suspension in Formula 1.
We've seen that Red Bull is running what looks to be huge amounts of anti-dive, and so many people and outlets, in my opinion, are giving this a lot of credit where it's absolutely not due.
Then again, the Mercedes upgraded car from Spain also has a LOT more front anti-dive, so what's it all about?
I break down the practical implications of anti-dive suspension in Formula 1, but also I'll point your attention to something that I think is related, but far more interesting and powerful.
Enjoy!

[@Arek-nb9pt]

As someone who is watching f1 for almost 20 years now I understand why F1 journalists are looking for a silver bullet solution in the car. We used to have tuned mass dampers, F-ducts, double and blown diffusors, split turbo and so on - single solutions granting huge advantage. Now with proscriptive ruleset that we have RB found advantage because they designed a great car where everything is working together and transplanting any single solution to other car won't automatically make that car faster. People are calling for a rule change to nerf RB, but I don't know what can be done without major change coming 2026. Whatever F1 decides to throw at them before will most likely hit other teams more than it will hurt RB similarly to what we seen with ride height change.

[@captaintoyota3171]

THIS. Changing rules b4 26 only would make gaps larger. Leave rules alone and teams will get closer n closer. As a f1 fan since early 00s i can tell u grid from 1st to last is closer than its been in decades

[@KevinJDildonik]

@@captaintoyota3171 Lots of people (even pundits) don't seem to remember how Merc came to dominate the hybrid era back when the new engine came into effect. Merc made an engine that, right out of the gate in testing, was massively more reliable and powerful than competitors. This gave them a lot of time to refine the car, running excessive downforce to use the power to make a more drivable car, while other teams were catching up. Basically - they started with such a big lead, all they ever had to do was maintain it. Red Bull and Ferrari both caught up to Mercedes in 2018-2021. Ferrari seem to have done it with an illegal engine (2019 ruling), so it set their whole program back when they had to get rid of their tricks. Red Bull did it with good old... er, money... but also general good design. There are always 2 ways to dominate an era of F1. Ferrari (and Mercedes) style, you can find a loophole in the rules and pray it remains legal. Red Bull style, you can iterate on a proven concept, which is less expensive and less risky. Given the CFD and money caps, I think Red Bull just played the game better here. It's not that Red Bull is the best car, it's that Ferrari and Merc screwed up. That gives RB a huge head start to iterate on the car while they catch up, just like Merc in the previous era.

[@RedmondBarryII]

An article with the headline: "Red Bull dominates because of full package." Doesn't get the clicks one with "THE reason Red Bull dominates" would get.

[@alesksander]

Yeah no silver bullet here indeed. Very reminiscent of Ferrari in 2000s. No really any strong point of car or solution to rule them all stood out. Those Ferraris were really well engineered. Just like those two ground effect Red Bulls, RB18 and RB19. And i m having no doubt that theirs grandchild RB20 will be monster too. No magic anti dive suspensions or floor designs or big undercuts its just "death by thousand cuts". Masterpiece.

[@lefturn99]

We looked at anti dive and anti squat in the 70s on our dirt track cars. Anti squat can give you a great traction boost on exit because it forces the tire down into the ground, making more traction. But it's tricky. If you dial in too much, it will launch hard, but run out of suspension travel (and extra bite) before the tires have enough traction. So we had to tune the anti squat to the track. Anti dive was important but not as much. Too much anti dive will lock up the pivot points of the suspension, which brings the effective spring rate to infinity. Thanks for bringing up something I have not thought of for 30 years.

[@brrrake]

It's such a cool topic - Very interesting insight from you as well!

[@druginducedfeverdream1613]

The Anti/Pro Squatting techniques you talked about probably explains how Mercedes were able to achieve their diffuser stall back in 2020/2021. Those are some of my favorite onboard footage of suspension, watching the Merc jump on the brakes at the end of a straight and watch the rear suspension assembly lift

[@ThijsSH]

All cars had the lift at the end of the straight due to the rake setup. Mercedes also had a neat rear suspension trick that lowered even further after a certain load at high speed resulting in the diffuser stall.

[@SkylineBNR34]

@@brrrake can you now make a video on mercedes upgrade in 2024 of the rear suspension?

[@rolandotillit2867]

There's also the mechanical balance between front and rear axles, oversteer setup puts more load on the rear axle, understeer more load on the front. This can lead to a situation where the front axle doesn't generate enough temperature limiting ultimate grip, and vice versa. Another issue can be from the tires being just on the cusp of being in their working range, and this can lead to balance shifts mid corner as the tire is out of the window on turn in, and turn in balance is ok, but then goes into the window mid corner creating oversteer balance mid corner, then understeer balance on corner exit as the rears come up to temperature, and the fronts fall out.

I’m a sim racing newb who was able to “afford” a BAC mini in GT7, and all this talk of suspension geometry, ride height, aero balance, etc, is helping me understand how to get a feel for tuning the cars in the game. With a couple of upgrades to my setup so I actually have a solid mount for my racing wheel, I have a feeling the back half of this year is going to be a lot of fun for me as I’ll be able to actually enjoy the reward for some of my efforts. Just for laughs, I’m currently rocking a racing wheel that sits on a jank, homemade, race wheel mount that consists of cobbled together PVC, tensioned nylon rope, and a modified couch desk. It **technically** holds the racing wheel in **a** position, but the setup is not rigid, and the force feedback causes the entire thing to dip and dive like luxury vehicle comfort suspension setups. Being able to upgrade to a proper mount means I can suck because I suck, not because I suck on a wheel mount that’s barely more rigid than a pool noodle.

[@f.kieranfinney457]

I think the more interesting question about the rear suspension of the RB is how it allows for so much squat during DRS (a soft suspension would do this) while still resisting extension under braking (a stiff suspension would do this) AND being more compliant than any other car (high anti-dive would limit this) without upsetting the performance window. That combo is the secret sauce.

Good technical explaination👍

[@zlm001]

I still think the suspension was a key to their success that others overlooked. Without it they would be much more limited in their ability to fine tune the setup to maximize their efficient aerodynamics under many different conditions. I heard Adrian spent a lot of his time focusing on the suspension. The suspension was one of the weakest links and limiting factors in deploying the aero designs that produce the fastest lap times with these regulations. I also think that Red Bull's broader range of operating windows, plus the extra compromises that the design allows them to consider, may explain why some have said that they take longer to get the setup dialed in during practice.

[@f.kieranfinney457]

The field were busy focusing on the aero and ignored what the new cars would do to suspension and how that would impact the oh-so important ride height (and by extension downforce). Having a designer with experience in the first wave of floor-based downforce was huge. Where will RB go when Newey eventually retires?

This is the first video of yours that I have seen. I liked it a lot. I really loved the photos of the suspension arms at very different angles for different tracks. I wondered why you didn't address the heave spring that is in Formula 1 suspension. The heave spring is a new one for me but isn't the reason for its existence to resist the dive of the front end? Also, couldn't it give anti-dive performance without impacting the rest of the suspension geometry? I'd be interested to learn more about the use of them. Thanks.

[@patricioharolopez6560]

Amazing video and explanation

[@jozsefmolnar6453]

I noticed a possible mistake. The lines for the anti-dive representation should be shifted to the upright pickup points. So you draw a line between the two chassis mounting points, and you have to make a parallel offset to the upright connection points. Great video btw.

[@stephensegal5187]

I always just used the intersection points of the A-arm mounting geometry to establish the mechanical amounts for dive and squat. There's a lot of other things going on here all at once with a ground effects floor compared to a purely mechanical grip design. You must first decide WHEN you need mechanical induced grip, and when you need more or less aero assistance. I always worked backwards from "Polar moment of inertia" in order to establish and define "what, how much, and when" through a given corner. I could add more to this amazingly excellent presentation, but alas Adrian is my biggest hero, and I would never want others teams to gain better understanding. I can tell you that McLaren is sniffing harder and deeper than anyone else, Thank you Blake for this, now I know exactly what Adrian is doing. 😀

[@driftmanwrx4837]

Intrestingly similar front suspension geometry we use on off road vehicle. To minimize pitch and roll but also because during the compersion the wheel moves back and gives more contact time with the bump , which means less force on the wishbones and chassi. Really nice video!!

[@whereswaldo1191]

I have always thought off road buggy racing would benifit hugely from decoupled suspension, I would assume it is legal. There are KZbin videos on it, it was used for F1 but I think it is well suited for long suspension travels. I could be 100% wrong but it's worth a look maybe.

When I was 16 I got a Vespa Piaggio Ciao (from 1965 me and the moped lol) moped it had front suspention that while braking made the front go upwards, that did not feel right because the front then went stiff as well. That style of suspention felt and was dangerous, I already thought it would be similar to my old moped suspention and of course it is just improved to just stop nose dive instead of nose up like my old moped did under braking.

[@NielsHeusinkveld]

What isn't made clear in most videos is that an 'anti dive' suspension comes in many shapes. You can have 100% anti dive with a nearly horizontal upper wishbone, if you angle the lower one a bit. But 100% stops the front suspension moving upwards, the car still goes down from tire compression. Just eyeballing the latest 'anti dive' suspensions, they are far greater than 100%, so that the suspension actually moves DOWN when braking, and the CAR stays at the same ride height because what the suspension moves down, the tire compresses from the load. Of course a split second later, you've lost 50kmh and the ride heights will go up as aero falls off, brake G force and thus load transfer is reduced, and the front will inevitably rise..

[@tuicks11]

Ferrari have a very "peaky" car but have good traction and top speed.

[@KevinJDildonik]

Ferrari have been notorious for pushy front ends and peaky handing in their F1 and supercars for literal decades - it was a massive problem in the prerelease Enzo. It was a big part of the problems Seb had with the team. Circa 2018 they were looking dominant thanks to what would prove to be an illegal engine, and that's what really set back the team. I think the 2018 engine concept was the basis of the 2022+ program, and when that got axed, the whole development path disappeared. These are systemic, lingering issues at the company. One suspension upgrade won't fix the culture problem. Now maybe if they stop axing team leadership and let someone like Vasseur do his job for a few seasons...

Angling the upper wishbone mounting down tends to LOWER the intersection point of the line drawn through both wishbones. The further the centre of gravity of the car above that point, the more dive. Therefore, surely the change is moving towards increased dive ? Of course, we don't actually know where the C of G of a a F1 car is.

[@AndyFromBeaverton]

11:17 When I talk to Adrian on the phone, he sounds more like Charlie Brown's teacher.

[@brrrake]

HAHAH yeah!

[@whereswaldo1191]

I would have thought high anti dive numbers would loose out to the loss of increased downforce from the increase in angle of attack of the front wing. Then I would assume you would set the rear anti lift to control your skid plate heights. The high anti dive would also increase stiction and then require increases in unsprung weight/strength of components to transfer additional loads to fixed geometry. It sounds like a statement but it's more of a question 🙂

[@WSW0424]

Incredibly detailed. After watching this I can see how easy it is for a top team like Mercedes to run into that porpoising problem they had last year. Do you think it was more of an aerodynamic problem or a suspension design problem? Or both lol

Rear anti squat would change drastically if the braking force was from the upright mounted caliper vs the inboard mounted MGU. I suspect they may choose from the two braking forces based on which is best for the next turn.

[@brrrake]

Excellent point, however the braking torque is usually split fairly consistently and energy recovery is paramount. I believe you're referring to anti lift or pro lift - the braking torque reactions

[@f.kieranfinney457]

Maybe they just tweak the ratio at each brake bias setting. There’s no way drivers could switch front-rear bias at every turn AND switch the rear ratio while braking, turning and fighting? They’re not allowed to have GPS based input for any system adaptations are they? The tech has existed in road cars for a decade so it’s doable. But I thought they could only gather data and not use it to adapt on the fly. They certainly can’t send data from the pit.

[@turbo_brian]

I feel like operating window is a more generic term to describe a multitude of things. A given car may have a narrow operating window for something like toe as that feeds into how much energy goes into the tire and the brakes may put more or less heat into the tire so another car could like different toe values even with the same tires. Other things impact this operating window but in general when I hear operating window I think of everything from aero to suspension to even something like the renault engine having more low torque and operating better at certain speed corners.

[@brrrake]

Operating window is used to describe generic things like ride height or aerodynamic states where the car performs. Or a tyre may have a temperature operating window. I have never heard it used to describe toe settings or smaller details?

[@dsdy1205]

Could it be that the gains are more evident from a user-friendliness point of view? If anti-dive gets you a smoother, more consistent downforce curve through a heavy-braking corner, then the driver is going to have a lot more confidence chucking it in there

[@brrrake]

This entirely depends on the shape of the aeromap and everything else. I don't think it's remotely first order.

[@barneyklingenberg4078]

The high center of gravity is annoying but in F1 not the main thing, Especially with the current ground effect cars. You want to be as low as possible at all times since that would increase the downforce of the floor.

This is not strictly true.

Hi Blake! I know you`re not an aerodynamicist but could to tell us had the leading edge of the Venturi tunnels (the downwash ramp under the air intake of the sidepods) is designed in such a way that it generates load/downforce at the same vertical plane of the CoG, or CoP or just for pure aero reasons?

[@brrrake]

I couldn't say

[@turbo_brian]

Anti dive increases the chance you lock up the inside tire while trail braking. For non aero cars you usually change your driving technique for a change in anti dive. If you're racing with someone with a lot more anti dive than you, it can be adventageous to push them on late braking lap after lap to try and initiate this locking as one it happens it is more likely to each successive lap and will push their braking point further back.

Another great video, but I have some feedback if you would like it. -The various lights behind you make for a pleasing, non-boring background but I would turn off the one shining directly on the panel behind you, in my opinion it's too close to you and too close to the panel (making for a bright, defined spot as opposed to softer "mood lighting") and becomes a bit visually distractive. -The intro sequence highlighting "dominance" was very well done, but some of the shot transitions were very bright and perhaps a bit prolonged, to where it becomes a bit jarring in the otherwise well edited sequence. -I'd remove the sound effect when transitioning between shots (from about 0:40 onwards) altogether. Personally I think it detracts from the audio "experience" and is just distracting, the low volume background track is plenty enough to keep it from just being a talking video and I'd stick with just that. Other than those things, the video is well edited, the "set" is well designed and you keep improving as a host, already on par with or better than all the seasoned F1 youtubers in my opinion, as you come across as very knowledgeable (which you clearly are), engaging without being over-the-top energetic, and the way in which you speak is very well suited for being on camera. Keep it up, you're already running an absolute must-subscribe F1 channel.

This feedback is very thoughtful and eloquent. I'll take some notes. I know it takes time to write so I really appreciate your criticism and feedback. And I also appreciate your kind words as well! Thank you. Some constraints of filming in my small space are difficult but I'll see what I can incorporate. Thank you!

The new graphics look great btw.

Real quick question, and this is something I've thought about when it comes to anti-dive, is wouldn't the front wing actually lift upwards after the initial braking since downforce is being lost on the front wing which would prevent it from slamming heavily into the ground? What is also the point of the heave spring if anti-dive is incorporated into the design of the car? Could it be possible to negate a lot of the anti-dive's potential by simply utilizing a stiffer heave spring?

[@brrrake]

When you brake there is load transfer which further compresses the front and the rear comes up, which causes the front wing (ahead of the front axle) to dip further. Stiffness and ride/grip limit how stiff the car can be.

[@brandonjoice1835]

The teams can do any sort of aero work they want and dial in the floor as much as possible ect. But theyll always be a leg behind. I was wondering how big of a deal it is that theyre the only team to run pull/push rods when it seems that that sort of set up is giving them everything they need. Everyone hails Adrian as an aero god, but i feel like car setup is still his ace in the hole.

[@brrrake]

Adrian doesn't really do any car setup work.

[@dantton1987]

Mindblowing how complicated this subject is. How do you account aerodynamic balance and car attitude while trimming the setup for a driver's liking? How does slow and fast bump/rebound come into play? What about bump stops? There's just an overwhelming ammount of variables. I guess that's where the truly great talents like Verstappen and Alonso shine (even Hamilton falls flat in that regard, IMO). Just give them whatever and they will figure it out. There's a reason why Senna himself said Jim Clark was the greatest of all. The man avoided messing with setup and prefered to just adapt. I can't compliment you enough. AMAZING video.

[@wiegraf9009]

The teams have historical data to work with and get to spend tons of sim time prepping before and after FP sessions. They also get to know how the car generally behaves.

[@brrrake]

How much time ya got? I'm actually working on a "how to set up a f1 car video". Stick with me. It's actually not insane once you isolate which variables you want to work with

[@phillipwathitu3505]

How many factors do engineers have to consider during a race weekend? 7 minutes into the video and my brain is begging me to go slow!! And we are only discussing what could possibly be just the tip of the iceberg. Great video this!!

[@brrrake]

All of these concepts, if they are new to you, sound overwhelming. Setting up a car for "the window" is fairly straight forward and I can get a rough setup for a new circuit in about 25-30 minutes prepared for the simulator. Past experience and knowledge is also very useful. it's not like "Computer please optimise"! This is certainly the tip of the iceberg, and I'm not sure how much further I can go before alienating the entire enthusiast F1 audience 🤣 I'm glad you enjoyed it!

[@Son0fFalse]

You are not the only one. He was talking about a high variation in ranges of setup that affects other components. My mind works on understanding square one of all setups before going through hypothetical setups and variations

[@phillipwathitu3505]

@@brrrake I understand. But once in a while maybe you should throw in a video like today's video where you explain some relatively complex details about a formula 1 car. I personally would like to know more about the chassis of a formula 1 car. How important is it? Why is it one of the top secret parts of a formula 1 car? How can it be a performance differentiator in this modern era of formula 1 cars? How does the chassis link up with other parts of the car, particularly the suspension to bring performance?

[@alfistibrasiliani]

with an anti-dive suspension the car can run lower (the proof is RB's wood plaque around the titanium always wears more than other teams, it's darker/with more scratches) and running lower means you can extract more downforce. That's the reason why TD39 crippled Ferrari last year...

[@brrrake]

Red bulls floor is darker because they paint it black to see where it's wearing better 😁

[@frankphillips5533]

I have a copy of Van Valkenberg's race car engineering. I understand the way and why of how anti-dive works. However I found your graphic's a bit confusing (lines of force - not the graph's).

[@brrrake]

I simplified it enough to gloss over it. Maybe vehicle dynamics course one day 😅

[@brrrake]

It's kind of hard to explain the details of it quickly without boring a lot of people so I kept the explanation short and probably cut a corner just a bit

[@alpha007org]

In my sim racing world (iRacing, ACC), you want some front compression, and rear lift under braking, so that you can rotate the car. I would think front anti dive takes away some feeling what the front end of the car is doing. (That would explain Perez Monaco crash, and a lot understeer moments in Free Practice sessions, where they are working on a setup and tyre sims.) Also, you want your car to squat under acceleration so that the tires have maximum grip. Next, anti dive has to be seen as a small component of the aero platform of the car. True, you have a more stable aero platform with anti dive, but my thinking is that you're hurting in slow speed corners. Extreme Anti Dive makes sense only if you consider the whole aero platform/package. Just copying anti dive on any other F1 car, I would think, would NOT be beneficial, and would only hurt them.

[@wiegraf9009]

Checo prefers an understeery car, and the RB19 supposedly is that, so it's consistent with strong anti dive.

[@dzjad]

This. Is. Awesome.

[@roflchopter11]

Excellent channel and content! 13:00 unfortunately this isn't quite right. Anti-Squad or anti-dive, or even roll centers don't actually change the amount of steady state load transfer front to rear or left right (except for the minuscule change due to moving the CG as the car pitches and rolls. What does change is the timing of load transfer. "Anti"-geometry and roll centers above the surface of the groud cause some low transfer to happen immediately, instead of having to wait for suspension velocity (dampers) or suspension displacement (springs, ARB).

[@brrrake]

Thank you! The video is correct... And you are also correct. The anti geometries do not change steady state load transfer. BUT they do change the displacement of the body relative to the wheels. For example. A higher roll center (while still below the cog) will reduce the steady state roll angle. The loads steady state will remain the same. However a larger portion of the transfer will be through the suspension and chassis - which will be unsprung and undamped. So yes it will change the timing of the elastic Vs inelastic portions of load transfer in transient. The steady state loads won't change. But the roll angle will be reduced.

[@harriettarandomina5275]

Slightly off topic: Had Redbull got a bendy floor?

[@ktwei]

How does anti-dive take away brake feel?

[@brrrake]

It entirely depends. In some cars, it doesn't make much difference. In others, it can have a big impact. But in F1 the brake feel related to anti-dive is a 2nd or 3rd order effect - not really a factor.

[@davidaugustofc2574]

In F1, I believe, the brake by wire changes everything, because the drivers remember very well how much force to apply to the pedals instead of how far to push the feet.

[@void_snw]

@@davidaugustofc2574 only the rear end is brake by wire, and that's also done through a hydraulic system with a pressure sensor.

[@procatprocat9647]

Drag racers use >100% anti squat to dramatically increase rear grip off the line using weight transfer

[@sspacegghost]

are there any counter intuitive concepts in suspension setup - you see it in sim racing, you can sometimes do the opposite of what youre supposed to and it gives interesting effects.

[@brrrake]

Hm. One instance I've seen is something like going stiffer on front roll actually increasing front end. A stuff front roll will tend to understeer as it increases load transfer on the front axle. However if the aerodynamics sensitivity of the front, let's say you have a very sensitive splitter, is very high, you could gain front end because you gained aero load from rolling less

[@sspacegghost]

@@brrrake so is that about torsion - and not flow ? The energy stored in the shape changes ? i often wonder how much aero is torsion, the twist....the divide between laminar flow and chaos is the effect but the cause can be hidden

[@brrrake]

@@sspacegghost in that instance it would be "the splitter is performing better so we have more front load"
