How To Use Brake Bias - Sim Racing's Secret Switch

[@dannyleeracing]

Just to inform you guys, Race Anywhere have recently narrowed the range of items that are eligible for the 5% discount, now mainly applicable to Pro Sim Rig and Race Anywhere branded items (rig components). Sadly, this means the example shown in the video (5% off a simucube base) is no longer possible. It's a shame and I can see why it's no longer possible, but I have to let you know so you don't feel as if I'm misleading viewers and baiting people with a deal that can no longer be got. What third parties do with their discount programs is totally out of my hands and all I can do is inform you of the change. Thanks for your understanding...

Wow. This is probably the clearest video on BB i have seen.

Indeed, very clear. Great video, thank you!!!

[@racekraft]

What an awesome video. Love the background footage! This other video talks about when you’ll need to change brake bias in a bit more depth. Really good info when paired with this video. Why you NEED to change Brake Bias [SIMRACING TUTORIAL] kzbin.info/www/bejne/i3yVpJ9mhdRgZ6s

[@_Arthur-]

Yep, very clear! Thanks!

[@MrRicardoMaravilha]

I agree

[@VishnuRajam4x4]

Additional point: Brake bias also affects tire temperature and therefore overall grip of that tire - more temperature means less grip. For T1 at spa for example you want a more forward bias to not heat up the rears to give you maximum grip for accelerating up the next long straight.

[@not.a.doctor]

Too much heat, not more temperature (temperature is just a measurement), and not enough heat can both hinder a tire's performance.

Thank you a lot! I did not notice it, but my brake bias on AC with the AMG GT3 EVO was standard on 71%. Now changing it between 52 and 54%. Laptime on Redbull Ring GP went from 1:32.80-1:34.00 to 1:30.00-1:30.90 on my first 15 laps, trying this out. The Lap record now is 1:29.792. Great video!

[@dannyleeracing]

Wow, yeah, that would've been killing your car's balance!

[@forbiddenera]

Oem cars are always heavily front biased and you generally want front bias anyway as your fronts will always have more grip on brakes so easier to lock the rears. I'm surprised anywhere near 5050 is drivable but I've never used iracing. But most cars in ac (and actually all other sims/games i play) I end up between 65-75 front usually.

[@CaptainCrunch99]

This is probably the best informative and graphical pleasing bias video ever made. Nice work !

[@dannyleeracing]

Thanks man, hope it helped you!

[@iangordon8078]

Great coverage of the most important topic in racing. Here is another tip. During a long race for tracks like Spa or Fuji turn 1, where you have a heavy brake into a hairpin followed by a long straight where corner exit is so important and cars without TC like PCup or formula cars. Moving the Bias forward just for this turn to keep the rear tires cool can help you get better traction getting back on throttle. It is another tool for the tool box when solving problems on track during a race. Managing tire temps through Brake Bias is yet another dimension of choosing the best balance between safety, rotation during cornering and traction on exit.

[@church493]

Bits missed: 1) in sims that simulate rain, the more wet>the less grip>the less mass transfer - more rearwards/closer to 50/50 bias optimal 2) if one is to heat brakes with brake dragging during formation lap, as there is no mass transfer, again, move brake bias to rear to not overheat fronts/for more even heat up (NOT forgetting to move it back to normal prior start)

[@oppenheimer11]

About the point 2 why there isn't mass transfer?

[@church493]

@@oppenheimer11 when you go at constant low speed (during formation lap) you don't accelerate/decelerate = no front/rear transfer. Low speed = negligible side-Gs/insignificant side loading.

[@oppenheimer11]

@@church493 thank you. Can i ask you another thing please? I'm confused. At the very end of the video he said to increase bias to add understeer and decrease bias to add oversteer, but shouldn't be the opposite? If I increase bias the front will have more grip, thus there will be more oversteer, and viceversa if I decrease bias. Am i wrong?

[@church493]

@@oppenheimer11 "increase (fronts) braking bias", make "more front biased braking" for fronts to brake more .. but also easier to lock/loose traction first with locked fronts "pushed outside of turn" .. thus understeer. "decrease bias", "less front-biased" - rears easier to lock first and and if it's mid-turn (as usually is during trailbraking), extra rotation or even rear lock/slip (think of like pulling handbrake that locks only rears), thus - more oversteer. You don't change grip by changing brake bias. You change which end will get braked more/are easier to lock/slip first and thus propagate more understeer or oversteer.

[@oppenheimer11]

@@church493 thank you for the explanation. I was interpreting it as more brake in front = more grip on front tires and more brake on rear = more grip on rear tires. I guess i was wrong, even tho all the explanation in the videos seemed to comply this idea, maybe I've just misunderstood since I'm a total beginner

[@luismigueldias2425]

Awesome video, Im getting to understand brake bias much better. I didnt think it would affect the driving experience so much. A must watch if you are new to Sim racing.

[@chrisvanegmond3157]

Thanks, really great, clear and concise guide. One point I would add is that over longer races, depending on the car you might be shifting the brake bias over the duration of a stint, as the car gets lighter on fuel. Depending on where the fuel tank sits, the front or the rear of the car might get lighter so you may slowly shift bias away from that side as the car gets lighter, to preserve similar behaviour.

[@pedrosilvaproductions]

Brake Bias was something I thought I should change once in a lap and that was it, and that it wasn't something that important. After I started thinking about how I could make my car brake better or more stable during specific corners I soon realized how much it meant for lap times. I improved significantly after doing so. For example, in Spa, at the first corner and the last chicane I needed to have higher front bias in order to help the car brake better but have less of it for other corners because I needed the car to rotate and not stop as much. That alone made me shave about a second off a lap

[@dannyleeracing]

That's awesome! A perfect example of how you can find the gains that seem impossible, just by giving everything a bit of thought and effort. Thanks so much for watching and commenting, too!

[@BabblingBubbles01]

I've been play GT sport and now 7 for thousands of hours. I use BB for a few situations. You covered them well. Even showed demonstrations. Thank you for your help. But I've scoured the internet for someone ( A pro) to confirm and or have so much time in that they've found this little trick....and you DO NOT mention it either. So in the RAIN. Put BB All the way Foward to the fronts and you will stop without slides ...full pedal. So far I kill it in the rain just because of my braking technique. I challenge you to try...and tell me what you think. If it's food enough.....maybe a how to vid? Thanks

Thanks for the video mate, I used the brake bias in the opposite way of purpose, I always thought it would make it easier to brake bringing the balance to the front, but last weeks I found that last laps of the race I'm losing so much time in braking, not being able to stop the car like at the first laps and rivals cut distance, it's because I needed to be moving to the back instead of increasing, very interesting

[@codywaldron2486]

As an avid iRacing circle track/NASCAR racer, I use brake bias all the time to loosen (induces oversteer) or tighten (induces understeer) the car up to rotate through the center of the corner better. As mentioned in the video, in a fixed setup series this often the only thing to play with tuning wise. If you can grasp how to use it to your advantage, you’ll find success.

Great video! Thank you! I 've been challenging myself to vary Brake Bias before watching this video, but was overdoing it.

[@MrHaggyy]

Brake Bias is also a mighty tool to get your tires in the right temperature window. If you start with cold tires you want something that's "50:50%", so each tire gets equally heated. This kind of depends on the car, Mercedes and BMW have more weight on the front so more help on the rear is needed, Audi is well balanced, McLaren or Porsche need help a tthe front. It also depends on the track. If you have long fast corners you need to watch rear, if you have a long straight or slow corners your front might get too cold. Once the tires have reached their window and you can keep them in it, you can use BB for performance only. Or you start easing of the load from the hot tire onto the cold, so you can extend your stint longer into the race. That's really crucial in endurance racing where too much rubber on one tire means you didn't used all of the potential grip you carried around all stint. But like everything in racing this has it's limits. In Mugello and Barcelona it's impossible to keep the front left alive until you used your rightside tires. And at the Nordschleife or in Dubai you have most likely cooked your left rear first. But at shorter tracks you can gain a lap per stint and at long tracks like Nordschleife or LeMans you can preserve tracktion for the long straights. On any track you can use BB offensively to trailbrake longer to get the move done under braking ( higher value, faster for longer), or you preheat your rear for better traction (lower value, outdrag your opponent out of a corner). In similar fasion you could use it defensively to counter the door. But this is a double edge sword as it makes you vulnerable to the unsuspected attack and costs you laptime. ^^ best defense is always just to be faster.

[@awsomef2004]

Not sure about the shift brake bias rearwards to stop at hairpins. The reason brake bias is sent forwards (beyond stability) is weight shifts to the front wheels, and therefore the front wheels can handle more braking force before locking up. Surely in a big braking zone, it makes sense to leave it forwards or even shift it further forward to brake harder and therefore stop faster before locking up?

[@dannyleeracing]

It's all down to the rears being under-utilised in most scenarios because pushing them to the limit of grip makes the car very unstable going into corners. If you're braking in a straight line, however, you don't need that safety margin and can ask for the rears to do a bit more work without fear of spinning out. Best thing to do is try it and see what you think!

[@suhdud4646]

So much time can be had purely because of braking. Im been learing to "feel" car alot more and looking at BB to aid that learning curve. My general race craft and pace is quite good but my braking leaves alot to be desired. What I also tend to do is if the brake zone is going up a hill, I will set my BB forward by 1-2 and going downhill I set it to the rear by 1-2. Going up or down in a brake zone already has the weight shifted to that orientation and the BB helps neutralize that already shifted weight.

Very goog and clear explanation of BB. Could you elaborate a little about BB and FWD cars vs RWD ? Thanks

[@spaceyamgaming]

Thanks, great advice! I knew decreasing brake bias would assist with turn-in but had no idea what percentages I should be using :)

[@DrR1pper]

The reason you're finding a bit more lap time by lowering the brake bias is because you're suffering from setup induced understeer, namely, too much rear wing. You're trying to alleviate said understeer by depriving the rear tyres of their ability to produce as much cornering force by placing greater braking demand on the rear tyres which then robs cornering force production. But as you've pointed out, it runs the very high risk of irrecoverably losing the rear. This is a solution to the problem but not the ideal solution as it lowers overall cornering speed carry potential. The ideal solution is to decrease the rear wing. Then you will no longer need to dangerously drop the BB.

[@DrR1pper]

The irrecoverable oversteer issue under braking is what we see of Sergio Perez who (relative to Max) prefers understeer which he gets with more rear wing and is a late as possible braker. And Max never experiences this issue because he doesn't suffer from the inherent understeer issue and is a softer and earlier braker, favouring a longer trail braking phase so he can build up to a larger yaw rate peak by his apex.

[@davidporeilly1]

Thankyou for your video. It was well produced and shared some valuable aspects of brake bias adjustment. However I will add some more vital information and query one or two points. Longitudinal weight shift: is greater in the BIG stopping zones. You brake harder for longer so the fronts are more weighted and so can handle more retardation. So it's in those where its more important to move bias fwds. Failure to do so leaves too much retardation to the rears that get lighter hence lockups. As such I disagree with your Hockenheim Hairpin example where you advise moving rearwards. The braking distance will be best when all 4 tyres are loaded to their maximum potential. So we are not in agreement that moving it rearward helps braking distance. On cold tyres on opening laps the weight shift is less as total grip/retardation is less so the movement of bias is ALWAYS rearward. As tyres grip up it moves fwds again. This is why the fronts normally lock up on cold tyres. Same principle when moving to harder/softer tyre compounds. The more tyre grip, the more fwds and vice versa. Worn tyres same. Tyre management: move bias away from the end that's wearing more or needs protection. Handling balance management: On this we are agreed. Fwds means understeer, rearward means oversteer. However IMO this is a feature to be used in partial braking zones vs big stopping zones. Finally the theory: The reason handling management works like this is that by tasking either end with less (longitudinal) braking duties frees up some more of the tyres finite contact patch for (lateral) cornering duties. So moving bias to one end makes that end corner less well. So fwds = understeer rearward = oversteer. Armed with this knowledge drivers can move bias within a lap and within a stint to optimise braking tyre wear and handling balance.

[@dannyleeracing]

Le Mans is a great example! I always use baby tea from the Porsche Curves right up until I drive past KFC. Then it's Builder's Tea for the heavy braking zones for the chicanes. Changing the bias twice per lap makes driving Le Mans so much more confident

[@adambrandt1858]

You have this completely backwords. Increasing front bias gives you shorter stopping distances and will put more weight over the front tires making more grip to turn in easier. While rear bias will stabilize the car car. Especially while trail braking so you dont spin out because of the extra rotation from trail braking. And those of you that think slip angle is how much the rear steps out under cornering youve been lied to lol. Theres no such thing. Slip angle is physical property of tire deformation when turn the wheel and the rim rotates but the tire resists twisting the tire and is know as slip angle. It describes how much angle the tire is twisting from the resistant part thats contacting the road and riesting to turn. What you describe as slip angle is just inducing a little bit of over steer and sliding the tiniest amount and counter steering. This just happens as you increase lap times and speed into a corner naturally. You should not be trying to induce oversteer at a speed which the car isnt doing it on its own. Itll just happen as you get faster. And you know two shits about cars your instict will be to countersteer just a little to keep it from losing it.

Great vid!! I know about this but too lqzy to think and adjust during runs. Do you have any guides as to which sections to adjust BB for tracks?

[@keeef23]

You are the master at explanation! Thanks 😊

[@dano824501]

Definitely using this on Watkins Glen bus stop

[@dannyleeracing]

Ask the bus driver to think about this at the bus stop

[@memoNo1719]

Very nice explained! 👍💪 Thank you very much! 👍

[@1hp-team343]

didnt understand, and now i feel like i can teach abt it, thank you very much

[@dannyleeracing]

Awesome, thank you so much for leaving your thoughts. Always pleasant

Brake bias doesn't make the stopping distance longer, in most cases it does the exact opposite. The amount of brake bias needed depends on the speed of the corner, elevation changes, and how slow the front suspension is, especially with a fast rear suspension (yes fast, as in how quickly it rebounds, not how firm it is. these are often correlated, firm being faster, however they are not the same parameters and are affected by dampeners) These 3 factors all affect how much weight is placed on each respective tire. Braking hard at high speed, braking down hill, and braking with a slow front suspension all result in significant weight being applied to the front wheels while being offloaded from the back wheels. This means that if maximum braking force is applied at 50 bias in one of these scenarios the rear wheels will lock significantly more easily than the front wheels because there is less traction due to the offloading of weight from the rear. As a result your braking potential is limited by the lowest common denominator: the braking potential of the back wheels. If you shift this bias forward you can get more braking power down on the asphalt and thereby slow down quicker. braking up hill, and braking with a very firm suspension benefit from a lower brake bias. If you watch a car brake vigorously uphill with a softer suspension you can often visually notice that the car will go from sagging at the rear to nearly perfectly balanced on both ends in braking which is part of why its so much easier to brake uphill (gravity pulling you down helps too). Braking in a turn with high front bias CAN cause more instability due to the fact that the front of the car wants to slow down more than the rear resulting in the front of the car becoming a pivot point. Braking with a really firm suspension just generally doesnt benefit as much from front brake bias because the weight shift is much much less. One cool trick with front wheel drive cars headed into a sharp turn is to tap the brakes so that the weight shift takes place and the front wheels have more traction to pull the car into the turn as you accelerate out, when you do this right it can take a turn that feels like a low traction corner and make it feel like you're on rails. on 4wd vehicles it's harder to maintain that frontal loading in order to improve cornering so front brake bias can help to force more weight to the front so that the turning wheels receive more traction while accelerating. Rally drivers use this technique a lot.
