Sim Racing Setup Guide 04 - Anti-Roll Bars

[@ChrisHaye]

Hey guys, thanks for watching. I've tried to keep these videos fairly beginner friendly, but if you have any tricks, tips or additional comments to add, please leave them in the comments - I'm sure there will be plenty of people that will be able to benefit from the collective experience of the community.

[@jajaboss]

Hey, Thank for making these videos man it's super easy to understand

[@russ2387h]

keep up the great work. this is what sim racing needs!

[@ChrisHaye]

Thanks Russ, hope the videos are helpful.

Can't say enough wonderful things about this series, fantastic job Chris! I'm only 4 videos in and already on my 3rd page of notes. This one was tricky for me to understand and I had to read the Wikipedia article and scratch my head to understand why these adjustments do what they do. It finally clicked when I realized that when you discuss softening/stiffening the ARB to affect understeer/oversteer, you are affecting the RELATIVE ARB stiffness between front and rear. Uneven ARB stiffness thus creates a twisting action about the car's axis which changes which tires receive the most grip. This also explains why some cars rear inside tire pops up off the ground during hard cornering. Cheers!

[@ChrisHaye]

Yeah, exactly that - glad you are finding the videos useful David. I really like the way you've described how this works. Relative stiffness is a huge component of under/oversteer balance, but absolute stiffness is still a factor as well.

[@Braindown73]

These videos are really useful, especially this one, I've now got a few tweaks in mind next time I take to the track!

[@ChrisHaye]

Thanks Brendan - glad you're finding these videos useful.

[@andyainsworth1802]

Simple and straightforward. Setups have always been a mystery to me, but these vids have made it far less of a nightmare for me. Many thanks.

[@ChrisHaye]

Thanks Andy, hope you find the videos useful

[@CaptJ03]

Awesome job on the videos. I appreciate how you get to the point, no fancy long intros and ridiculous music or flashy effects. I been sims racing since the begiing and still learned a lot from your vids. Thanks.

[@von...]

You are a hard-working saint. you should be proud of this series and yourself! You deserve so much more subs too

[@ChrisHaye]

Thanks dude, much appreciated. I hope people are finding the videos useful - but yeah, as you said, quite a lot of work! I might take a couple of days away from KZbin when these are finished!

[@von...]

Chris Haye it would be a much-deserved break, my dude! thanks again :)

[@rileywarps8289]

As a brand-new beginner to sim racing these videos are amazing and exactly what I'm looking for. I'm still struggling to get my consistency in Competitzione above thirty, so I likely won't have to worry about these things at least. But seeing someone clearly explain all the different terms which are hurled my way across Assetto and Dirt Rally 2 makes it so that when I wanna get into tweaking this stuff I at least have a vagua idea about what I am doing.

[@marse_17]

Chris, I'm loving this guide, just what I needed. Keep it up with this amazing content, you are one of the best sim racing channels in youtube. PURE QUALITY. Cheers.

[@ChrisHaye]

Thanks Dino, much appreciated. And thanks for watching

[@MrTimdtoolman1]

Another "home run" my friend. I really appreciate the time and effort you put into your videos, and this series is without a doubt the best sim racing setup guide I have seen on YT, (and I have watched quite a few) IMHO. Great work.

[@ChrisHaye]

Thanks Tim, that means a lot. It's such a complex and, honestly dull subject that I did worry that these videos wouldn't be well received. Glad to be proven wrong!

[@alsimoncelli7313]

Thank you putting this series together. I look forward to all your videos more then any other sim channel, and that’s not taking anything away from others. You just have a great way of presenting! Keep up the great work!

[@ChrisHaye]

Thanks for the kind words Al, they're very much appreciated. Hope you find the videos useful.

Thank you, You have the best video off sim racing on youtube, you are a good teacher. Thumbs up

[@ChrisHaye]

Thanks as always Crabby!

[@lunardawnimages6838]

New to ACC...really helpful guides, Chris!

[@SagaraUrz]

Good work, i was looking for videos to explain each aspect shortly.

[@devioushk]

Hey Chris, great job explaining the affect relative ARB stiffness between front and rear has on balance. What about overall ARB stiffness? Keeping the front to rear ratios the same, whats the overall desired level of ARB stiffness should we be aiming for? How can we tell that the overall ARBs are too stiff or too soft?

[@agoniavr]

Track and car at 1:50? Absolutely love the vintage look of it(even though I can never find online races like that)

[@jurgenbussche]

a beginners must watch nice job

[@CJDirtyEwok]

VIDEOS ARE GREAT, posted them to my club discord server they are that good.

[@ChrisHaye]

Thanks Dirty Ewok - hope people find the videos useful. And thanks for sharing dude - much appreciated!

[@Heldermaior]

Front roll bar stiffening can reduce turn in understeer in medium speed corners. Due to the lesser body roll you reduce the weight transfer leading to the inner tyre having more load during cornering which increases it's contact patch providing more overall grip. Circuits like Spa benefit a lot from a stiff front and rear (up to a point).

[@ArchOfficial]

Incorrect. Springs don't influence load transfer; apart from the axle that you stiffened relative to the other having MORE lateral load transfer relatively, with the other axle having less. Hence why more spring stiffness on the front will, if only kinematics are concerned, increase understeer. Body roll has nothing to do with kinematic load transfer, at all.

[@Heldermaior]

@@ArchOfficial ok, what has body roll to do with?

[@ArchOfficial]

@@Heldermaior It doesn't have anything to do with load transfer. The only exception is the very small movement of the CG laterally which will of course impart a little bit more gravity to the outside, and a little bit less to the inside. Even in vehicles with no roll, like a shopping cart, there is load transfer. The roll is just due to the deflection of the springs, it's a side effect. The car rolls BECAUSE load is transferring, and stiffer springs cause less roll not due to less load, but due to more resistance to the load.

[@Heldermaior]

@@ArchOfficial ok. Got it

[@MrWarringtonwolves]

very helpful thanks

[@acdcdave1387]

Thank you so much for this series. Quick question: if I'm in a powerful RWD car with excessive power oversteer like a V8 Supercar, would completely removing the ARB in the rear be acceptable or should I keep it and just soften it?

[@terrylu4894]

Thank you very much for the video! I can understand the the front ARB part, but still confuse at the rear ARB. I thought soften the rear ARB will allow more rolls hence put more weight at the outer rear wheel, causing the rear part to oversteer. why soften rear arb cures oversteer?

[@ArchOfficial]

Roll doesn't influence kinematic load transfer at all. If you soften the rear axle relative to front, you will introduce *less* lateral load transfer across that axle, and more in the front, hence understeer.

[@eSKAone-]

Thanks♥️

[@gtrob8711]

hey bro you have a good setup for the Bentley i keep on adjusting my setup but both front tyres overheat all the time for suzuka track plz ty

[@hectorcsg4624]

Hi Chris I need your advice. As you mentioned it’s better to change one setting at a time but if that first setting doesn’t fix the problem should I put it back to its original before going to the next one? Or leave it because the second one won’t work if I put the first one back I hope I don’t confuse you I’m asking this because I have heard that some problems need more than one setting to fix it thanks

[@ChrisHaye]

Hey Hector - yeah, that's the approach I take. It can be quite time consuming, but I try to develop setups over a few days/weeks, rather than in one session! However, you're right that some issues will need more than one change, but I still try to feel the effects of one change before I move onto the next. This is mostly because I don't trust myself - it's very easy to start being tricked by your senses... and the placebo effect is strong!

[@mehmetemretasci]

I am very confused. Because in iracing Front Anti Roll-Bar stiffness=more understeer (Formula 3.5 Renault). Which one is correct?

[@mrj3217]

Front engine cars should have -- Soft ARB in front -- Stuffer in rear right??? Just a little thought.

[@dotbags]

Hi mate. For ACC is softening = to a low number or a higher number?

[@pspuser1991]

You're welcome

[@NicoNice24]

thanks

[@pominozjohn2150]

Can you use an aviation throttle to adjust anti roll bars?

[@ImCookiiez]

I really love your setup series, it's a great help! But I do have a question: I thought stiffening the front anti roll bars would make the car more responsive on the front end and cause it to turn in more easily and not understeer because less weight is transferred allowing for a more direct handling. I can't see how that would induce understeer?

[@ArchOfficial]

Stiffening springs on an axle will cause more load transfer across that axle. Only relative stiffening, though. Absolute stiffness of both axles doesn't affect it.

[@oskarr3018]

What settings do you use for Anti Aliasing in ACC ?

[@ChrisHaye]

Hey Mr K - I've had to turn down to 2x AA, because I'm running 1440p triples, and that's a LOT of pixels for the video card to render! To be honest, 8x doesn't look that different to me at 1440p though.

[@oskarr3018]

@@ChrisHaye Ok, because when I use maximum FXAA, the game looks very blurry and jaggy.

[@cycata11]

I tried minimum and maximum settings for ARB and tyre pressure but i don't see any difference, car behaves the same lol.

[@hassannaeem101]

Often whenever I'm watching a yt vid I like to mentally calculated the like to dislike ratio. This video is by far the highest ratio that I've seen on a video and I must say it's well deserved, your videos are of great quality! For this video for every 750 likes your got 1 dislike.

[@anthonymanes1014]

I was always under the impression that stiffening the front ARB helped fight understeer on turn-in. I've been living a lie.

[@ChrisHaye]

Hey Anthony, there's a lot of misconceptions in this area - but don't take my word for it, this video by SafeisFast (featuring Jay O'Connell from Rahal Letterman Lanigan Racing) is a great resource: kzbin.info/www/bejne/a3vcfISvdrt2nKs

[@xr.spedtech]

Parts to control the car when the center of gravity shifts to specific portions of the car ...

[@ArchOfficial]

The CG doesn't move at all during cornering; load moves.

[@xr.spedtech]

I'd rather take sim racers seriously over Forza players ...

[@Goguvarra]

hello, Chris. Watched all these videos with great interest. One question though, the people here state that roll bars affect mid corner balance more and not turn in and out. Damping rate affect the corner entry and exit. suspensionsecrets.co.uk/sim-racing-suspension-set-up-guide/ WHy the difference. I suspect they are pretty close. Thanks
