I have 2 questions: 1.) Do you use a different TC/diff combo in a long race vs quali for tyre saving? 2.) Does double apexing use more tyres? Because I always thought the other way around because if you double apex and V the corner, you brake and accelerate in a straighter line and the rotation phase is shorter. Is it different with mid/rear engine cars where you tend to have your oversteer during the mid corner coasting phase rather than the exit?
1.) certainly, yes. say on nurb in quali it will be TC3-5, but for the race you'll try to use TC8 as often as possible on the BMW (I find it too intrusive in the slow speed corners) 2.) the problem is rotating the car, while asking it to accelerate at the same time. V'ing the corner helps to separate the rotating from the accelerating a little more. the mid and rear engine cars have the problem that they often rely entire on the rear tire (except the lambo) in all corner phases. The porsche always has colder fronts for example and its tricky to really utilize them without overwhelming the rear. here also or here especially the presented ideas will matter. and then its still very individual, even cars that are almost the same are very different. The lambo for example is VERY pitch sensitive, however the evo II Audi is not at all and also does not really change balance through a stint aerodynamically, whereas the lambo definitely changes quite noticably
When I was little and trained road cycling my only knowledge was the book "cyclist's training bible" by Joe Friel. I wish I had a simracing book written by Nils 💪🔥
I'm decently fast at acc, about 1-1.5seconds off record pace on most tracks so it's hard to find videos that aren't things I already know. This video was invaluable. So much info for those who are on their way to getting quick and those who are trying to get next level.
Thank you for the great video. As my lap times have gotten faster over the few months, I am starting to lose a lot of lap times after 20 mins into the race. Ex In Barcelona, on LFM 25min race, I lost about 1.5secs of lap time and the car had much less grip it felt like. I was having a really hard time keeping it together and finish the race. 25mins is just a sprint and I can’t believe I am destroying my tires this much. By the end of the 25min race my FL tires were about 2.5 mm FR 2.6 and rears about 2.5. To me that doesn’t look like a lot of wear? What do you think? I will give your driving advice a try, to be less aggressive.
depending on the car you have way too much wear on the fronts. the rear should easily be 0.2mm lower than the fronts. so looks like you're pushing a bit much into the turns. our "slip" channel in the telemetry data can reveal excessive slip on the front
After watching this video I thought about the things you said and incorporated that into my next LFM 45min at Silverstone. Biggest take away for me were not being so aggressive on the trail in and the throttle on exits. Much more confident for a longer stint now. Thank you for a great video man!
Great video Nils, I always learn a ton from your videos. Regarding rear wear in a long 45m or 1h stint, does it make sense to increase rear toe as well as the things you just mentioned? I have just started racing longer races and I am struggling with tyre wear in the Honda. It becomes very oversteery after 25 min or so. Many thanks!
it's likely impossible to keep the same balance over an entire stint. generally: the stiffer the car the less the shift in balance because there is less ride height change with decreasing weight (you can test this in the setup menu in practice mode using the fuel tester in the aero tab, just compare the ride height change with soft and stiff springs on different fuel loads). however that will also change the general behavior. in the end you will need a more understeery car at the beginning to get a less oversteery one in the end. toe can play a part in that
@@SimracingPopometer understood. I will reduce rake then to make the setup a bit more stable overall. Thanks Nils and keep it up, you have the most informative content on ACC!
Good video! Where does the popometer software get the data to build the line the car has driven around the track from? I always was under the impression data around car position was not shared by the game.
Yeah ACC doesn't write a car position into the motec file. some games do. but even then you wouldn't have the correct track width and exact shape cause you'd also need a calibrated one from the game in the same coordinate system
I have a race in 2hr from now with hot conditions where I need to save tyres, this is amazing :) But 1 question Nils. Do we need to change the max camber and max -ive toe that we usually use, for the race?
for stability its really only about the toe (i.e. reducing for more stability). cambers will almost always be max. It's hard to make an impact on tire temps with camber - your only option is taking care and using max ducts really. hope this advice comes in time for the race! :D
you would have to go even more extreme really. the rears wear faster it seems now and you will have to somehow try to use the fronts in order to not grow the balance apart too much.
I would like someone to explain the driving styles. So that I know more precisely what and how I can adapt. But I think that I have to find this out for myself. After almost 450 hours in Acc I still have to realize that I have no plan how to adapt setups to me. I expect to learn this in a coaching session. And thank you for sharing your knowledge
here are my 2 cents: there's always a best way around each corner for each car. no matter how many factors you want to consider for it, there's like a physically determined best way. There will be differences between games, which style is required or in very detailed games like ACC also the cars need different styles. But in a given scenario I dont really think there are different driving styles that lead to the same outcome. Especially I think one should only really speak of a style when it is something fully developed and chosen on purpose and not a workaround forced upon the driver by discomfort around hard to predict driving behavior of the car. So, while you can make changes to the setup that will mitigate some of the driving errors, the better way would be to get behind the driving first.
Yeah for me is other way around. I almost always wear front tyre more. And i start to wonder if is this because of locking and bias torwards front or something with driving style. Stints above 40 min kills my fronts and i AM loosing huge amount of lap time
yeah, you are most certainly steering way too much. the fronts are usually not the limiting factor. But on the other hand, if you are on a preset setup - i can't guarantee for anything, they tend to have terroristic understeer in them in an attempt for abundant caution for very new drivers. if you however force the issue on your own, then setup changes won't address it. only steer so much where the car still responds to steering input, once it doesn't respond anymore to more steering, theres nothing to gain when you keep turning
Hey Nils. Habe ich da was falsch verstanden. Der Porsche neigt doch gegen Ende eines Stints eher zum Untersteuern, da sich die Front hebt und der Aero-Grip eher zur Hinterachse wandert. Oder bin ich da komplett daneben?
Mate, this is one of the best acc explanation videos ever. Sometimes I don't think you are appreciated enough for these breakdown videos you do.
Much appreciated!

Not sim racing specific (and not written by Nils), but Ultimate Speed Secrets by Ross Bentley might be what you're looking for.

its in shared memory

Absolut brilliante content Nils, it really helps me to understand all the bits and pieces better!
Thanks for your work Nils, so much material to consider..
Very informative video. Thanks so much Nils. Much appreciated.
Will this need to be updated since the 1.9 update?

the usual problem is turning the wheel too much, way over the grip threshold. yes, also brake bias, and turning in under braking (instead of coasting)
yeah, you are most certainly steering way too much. the fronts are usually not the limiting factor. But on the other hand, if you are on a preset setup - i can't guarantee for anything, they tend to have terroristic understeer in them in an attempt for abundant caution for very new drivers.

nein, richtig. die Frage ist nur welcher Effekt überwiegt - aero? Masse? tire wear?
@@SimracingPopometer alles klar. Thx Nils. Jetzt bin ich beruhigt 🤣
