I feel like I just learned Santa isn't real.

[@DJYeeJay]

Santa's real but brake bias cheese was admittedly too unrealistic

[@OldguyChris]

Santa's not real?

[@STREET24000]

If Santa isn’t real, then why does NORAD track him????

[@coltontindle]

Notice I didn't say Santa isn't real, but rather that this news is so shocking, it's comparable to finding out that such a stalwart figure of society never even existed. Truly preposterous.

Nice to see you show your work and admit being wrong. Appreciate you sharing your knowledge and experience. 🎉

[@theonlylolking]

Eventually real life bugs are going to creep into the sim as simulators become better at simulating. Assetto Corsa Competizione accidently simulated a real life GT3 traction control bug. A traction control bug that was a realistic feature. I think the same thing shall happen in iRacing especially since you can put in far more simulated hours to find bugs than in real life.

[@CouchSlouch-]

Kudos to you for showing a strong morale character and being able to say you're wrong. Lots of people would not do that.

[@mbgmadbull1141]

I think it boils down to most racers being really superstitious. like Dale thinking a 50 dollar bill in his pocket prevented him from winning the 500. basically if you believe it works for you then it will work for you, thoughts and words hold that much power that it's almost supernatural.

[@Ootlander]

Oval racers specifically are notorious for being superstitious, they are the hockey goalies of racing.

[@mbgmadbull1141]

@@Ootlander I hate how accurate but funny this is XD so true

[@LithFox]

I think this is a common thing within iRacing. A lot of the times, it's hard to actually tell if there is a solid difference between mechanical differences and what is just placebo/approach/condition-based situations. There's a lot of moving parts in iRacing and while it's easy to say that something isn't doing something, it doesn't mean that something else isn't impacting you. It's super complex and why it takes a lot of time for iRacing to fix "what should be an easy fix!" a lot of the times. These myths are always fun when someone attempts to show their work though!

But it could be that you were wrong and had it reversed. high bb could be looser than tighter

That is exactly what I noticed as well. It would take longer, but I think there would need to be a larger sample size. The answers were reversed, but consistant.

[@JoaoLopes-1982]

Yup, if he had a 50/50 chance on each setup test, and got them all wrong, that shows statistical significance of the highest order! Just the relationship between BB and loose/tight is reversed

I simply don't interact with the forums. It's too toxic and pointless. I'll report bugs, but thats it. I'd much rather use a group chat, much easier to filter out the angry children.

[@A.P._eRacing]

the original question was does BB effect the handling of the car without using brakes. From what ive seen, even though you guessed wrong the 2 setups were loose where as the other is tight. We can all see it on video. Certainly looks like it makes a difference to me.

[@mavester]

I was going to comment the same thing. There's clearly a difference, at least based on what he said

I really appreciate you taking the time to do this experiment, but it needs to be said: Even if you guessed the correct brake bias setup after testing, it would not have proved that there was anything going on. Just that you would have guessed correctly. :) Great videos!!

[@777Reachout]

Props to you and your authenticity! The ability to admit when you are wrong says a ton about someone!

[@BGR_33]

I’ve felt this before on the road side of things. I’d adjust the brake bias in the garage, come out on track & the car or ffb would feel tighter.

[@iracingaussie]

Huge respect for owning it mate! I was with you all the way up to the last 2 minutes ha ha…

[@davidjaques9354]

I suspect it is down to what happens on the out lap, and where the tire temps end up when you start your timed lap. on the video, your first run, you ran a very low line, maybe took some extra out of the fronts, and on the timed lap was tight. next run you ran a much higher line on the out lap, maybe saving the fronts a bit, and on the timed lap you were loose. If you really want to pursue looking into this, I would say try a test using the exact same setup, and only change how you run the out lap. and if possible, save telemetry and compare tire temps (RF vs RR) so see if there is any correlation.

[@PazLeBon]

HMM, IF HE DID RUN DIFFERNT LINES THEN THE TEST IS POINTLESS

[@RaymondKenneson]

I noticed this from day one. I have only raced for 1 year. I watched your videos to get better. I started playing around with brake bias. I noticed different feels even on tracks where no brake was being used. My son, who has been on for 5 yrs, said I was nuts. I created 4 random setups on charlotte, and let my son run laps on my computer, and he didnt know what was changed. he noticed the changes right away. It does make a difference.

[@lasarith2]

Since I don’t drive iracing, I’d say - has there been any update’s in between this test - and when you last notice the difference, if so you’d either need an old build or they’ve changed something since .

[@DJYeeJay]

They just updated track surfaces which could have made this a bit more muddy, but I don’t believe I ran enough laps for that to kick in

[@brianwhitley]

Much respect for the humbling video, I'm with you I too feel ways about things and get it wrong or its just me thats feeling that way on things ...

[@MFR327]

I will say on the dirt side brake bias makes a HUGE difference. For example in the Dirt Street Stocks when the track is super super slick even when using no brakes even the best setup builders will max out the bias to give the car more center through exit grip. Same way you can connect the RF brake in the Dirt Latemodle to increase rear bite (Can be seen in the setup in chassis adjustments) ik in fixed officials a lot use brake bias and RF Brake connect to get grip and speed. Same way a higher brake bias + Quick downshifts in the pro 4 create a heavier brake feel.

[@CreamyItalian]

You are not wrong, the way you categorized your guesses was though. Your only reference was a neutral BB, no way for you to tell from 40% and 84% which extreme would be loose or tight. But what you did do is say test 1 was different from 2 & 3 and that was the original point, Brake bias changes handling without using brakes. You proved your point. Good job backing up your idea. Funny about the iRacing guy trying to discredit your claim by bringing up the countless times "tricks" were found and grass dipping @ Spa 24 was just around the corner.

[@zanetti20]

Was this recorded before or after the oval refresh though? Also could it be that it affects the leg truck differently then the arca/current truck?

[@DJYeeJay]

It was recording today, I don’t think I ran enough laps for the refresh to kick in, could be wrong

[@zanetti20]

@@DJYeeJay from what I've felt and others, the refresh has affected both warmer temps and colder temps

[@mrj3217]

Honest question here. Why do you not use the mirrors in car/truck? I notice a lot of people don't use them, I run a single 32 curved 1440 Azus tuf monitor and I get 230 fps to 150 fps at times constantly.

[@DJYeeJay]

Idk that was the default option. 99% of my iracing settings ive had since day 1 of playing. Thats why I give no one tips on their iracing rigs hahaha

[@zigzagbruno1486]

[@EvgeniySlipchik]

You guessed it wrong the way you thought. But you guessed it right the wrong way in 100%. Need to doublecheck the mirrored composition here.

[@V-Racing]

Huge respect for going through with the video and admitting that you are wrong, takes a man to admit their mistake.

[@BlackDogszz]

You need to do the test multiple times. I say this as getting 100% wrong is the same as getting 100% correct and 3 tests are not enough. Just cause you got it backwards does not mean there isnt a bias, just you got it backwards. Do more testing you dont need to release multiple videos but once you tested you will know for sure.

[@s1nenomine]

Also being 100% wrong could mean that it's the opposite of what everyone thought, to definitely make sure that there's no placebo we would need dozens of people at least to try several setups the same way you did (without knowing which is which) to find if there's recurrence. If most feel that 40% setups are tighter then that would strongly mean that there's something to look for.

[@billvarner6548]

I didn't really see enough to say one way or the other. Your steering inputs and driving lines were completely different for the first lap.

[@StudioDaVeed]

But you did show a difference even though it was the opposite of what you thought the result of the BB setting was.

[@allencountyrunner]

Tbh I think you may still be on to something because when your brake bias was lower your grip was a lot better in corners because both setups that your BB was high the rear end did kick out hard…so this could be a very possible glitch and we all know Iracing never admits their faults if we are being honest…I mean it was until last year they fixed the grass glitch and that took what 13 years and a huge live stream event for them to finally fix it

[@axemanracing6222]

I found a glitch in the matrix. Under caution, people were creeping into the pits, leaving several car length of space to the next car in front. I found out that it is possible to overtake (under caution) on the inside between the first pit lane line and the second line (where the speed limit starts). Until someone called out iRacing and they banned me for 1 week. Today you'll get an in-game penalty if you do this. I'm fine that they fixed it, but I'm still mad about the 1-week-ban.

[@DJYeeJay]

DJ LIe-J idk

[@TheFelloMello]

Is there not any software that can record input over time, and then recreate it? I think it would be cool for you to make one hot lap with settings in the middle, and record your inputs. And then change the setup, and be able to hit play on those inputs.

[@DJYeeJay]

I’m not aware of any software like that for iracing

[@jeremysumpter8939]

Wanna know what it is...Its coding, brake bias adjusts the balance of the car to simulate bb difference so yes it can be felt without touching the brake.

[@airblair7900]

I feel like this is real on many games. Not sure about IR, but it makes me believe that “coasting” is relevant to braking in the code, to some extent. Being, in many games brake bias does affect handling, but maybe the idea gets neglected and gets dragged around from sim to sim, causing a placebo.

[@arishakala]

That's actually an interesting theory; what if engine braking / resistance is what is affected by a change in brake bias?

[@kneebon5]

Clearly had credits added to the account and joined the lie so they dont have to fix it

[@DJYeeJay]

If I speak I am in trouble

[@wowTHATSgarbage]

Idk if it works in i-racing or not BUT this was a thing for top times on console (Xbox) gaming ! Forza etc etc we use to drop brake bias to go faster and since I've been on iracing I've kinda sorta thought it has made a difference a few times but I'm still not in-tune enough with i-racing to tell for sure or not 100. based on my console experience i'd say you're not wrong in assuming this is a thing that makes a difference in handling but idk if it does on iracing. It is a thing though ! Lol

[@xX_Gravity_Xx]

iRacing staff refuse to look into anything. When they do actually fix something, they end up breaking it again later down the line. I don't get it. There is clearly an issue with Brake Bias and vehicle stability. Now, how smthat issue actually manifests Idk. But that oddness is demonstrated here.

[@cayenne7792]

I was hoping to see some telemetry data...

[@HistorysRaven]

My one problem with this is that you knew which set ups were being used. I'm not saying the outcome would be different, but I'd like to see what happens with someone who didn't know the brake bias were going to be different. Or, if they knew there was going to be a change in brake bias, they didn't know what the different brake biases would be.

[@robertmerlino2312]

Since iracing engine is the old papyrus engine with some upgrades it carries over the brake bias effect that was well known way back when...I started with N3 and have continued since....Michigan we always went forward with BB to get into the turn without spinning

realistically this entire video is anecdotal, it could be a thing it could not be a thing, the only thing that wouldn't be anecdotal is a staff member checking on the back end... which they did, so it really just comes down to how much credence you put into that

I would argue that your experiment shows that there is an effect on handling with a change in brake bias, but not the exact effect you thought it was.

[@Il_Lans]

I'm not sure if iRacing has such a problem, but I'm pretty sure that when I spin BB, my perception of the world and driving technique change, regardless of the use of brakes. It's like I'm regulating myself with this adjustment. I am sure that psychology in racing, even if we are sitting at home, is a very interesting topic. but I don't want to know that I'm the hamster from the lab )) and I think that's why the iR staff doesn't always respond on the forum. they're just laughing at us)

Hmmm... Interesting though. Whilst you got your guesses wrong, the point of the experiment was to show brake bias makes a difference to the handling which your very limited data does seem to suggest. You should get a bunch more drivers to do the same test and report back on what they find. If 20 drivers do it, you've got a much better dataset to work with.

[@jacobevenson8702]

This is in need of a round 2 I’d say. You didn’t necessarily prove anything either way, just guessed wrong. You said the first one felt tight and the last two felt loose, well the last two were the same and the first one was different. Imo that proves that there is something to it.

Okay, ive got a new hypothesis id love to see tested then. Hypothesis: BB adjustments DO, in fact, affect the car while not under braking, but has an inverse effect to what the adjustment does under braking. Step 1: take stock set, stock set with min. BB, and stock set with maximum BB for legacy truck, current truck, ARCA, Xfinity, and NextGen cars for Auto Club, Michigan, and Charlotte and save each x2 under different file names. Step two: Have a friend repeat step 1. Step 3: Swap those files, discarding 2 of them per car/track combo. Step 4: both researchers should drive each of their 4 setups in a 5 lap stint for each respective car/track combo, then guess which setup is what brake bias. Step 5: compare lap times between each run. Secondary hypothesis: Legacy trucks being on the old tire model affects how the truck responds to on throttle brake bias respective to the current build. Data collected during research adequate to confirm or deny.
