Aristotelis, a member of the dev team at Kunos, has provided a good explanation on Brake ducts, car damage & tyre damage and how adjustments will affect performance within the sim that goes to great depths of realism...

ACC v.0.7 brings brake ducts simulation.

Actually brake ducts simulation was always there, but now it is enabled as setup choice. As usual the preset setups have a default brake duct setting, that can work safely pretty much in any condition, different brake duct settings can affect greatly the brake efficiency but also the tyre temperatures and of course up to a point, the aerodynamics of the car.​
The obvious functionality of the brake duct is to bring more or less air to the brake discs and keep them in a temperature range that can be effective. Setting 0 is a completely closed duct and can provoke brake fade very very fast, exceeding 1000°C. Never to be used in a real race, but added for simracer's gratification. Setting 6 is completely open and can keep the brakes very cold.​
Small and fast note of how the brake heat affects braking performance. The brake discs and pads have a range of optimum friction, just like the tyres. Keeping their temperature between this range, will give you the best possible brake performance. Of course that doesn't mean that it will also stop the car sooner, as this depends on a multitude of reasons like tyre grip, downforce, ABS, setup etc. But it is obvious that a very cold brake system will make your braking zones much longer and the same will happen for a very hot brake system. In addition a very hot brake system will also wear down the pads much faster... but this is a different story for a different release version maybe
The brake duct doesn't only change the peak heat temperature but, most importantly it changes how the heat gets dissipated after you release the brakes. A low setting will keep the brakes hot for a longer period of time after your last braking zone, while a higher setting will not only achieve a lower peak temperature but also cool them down faster.​
Ideally you want your front brake HUD to show green or slight yellow at the end of your braking zone and your rear, green. Don't judge after just 2,3 braking zones. Do a couple of laps and let the brakes do some heat/cool cycles to arrive at a balanced condition.​
MoTeC channels are available for brake heat.​
This behaviour brings us to the next very important influence of the brakes. The red hot discs will warm up the rims and then the air inside the tyre. In that way you can use the brake heat to heat your tyres up or try to run a bit colder brakes to keep the tyres from overheating.​
Again, a couple of laps are needed to check the heat behaviour of the whole system brakes and tyres.​
Also keep in mind that the brake ducts, especially the fronts, get heat from low near the asphalt. That is why they are influenced more by asphalt temperature. This means that you might have the same ambient temperature but an overcast weather will heat the asphalt and thus the brakes, more than a cloudy condition.​
Also, the water now influences the brake discs, so under rain conditions it is better if you use a lower brake duct settings.​
Finally, as you might have thought, the brake ducts will influence a bit the aerodynamics of the car, both in downforce and most importantly drag. The differences aren’t massive as you might expect, but they will make 3-4kmh difference at the long straight of Paul Ricard and as you know, every little counts.​
ACC V.0.7 also brings an industry first tyre damage implementation.
One of the most risky conditions in a racing car, is cold tyres. Everybody has heard pit radio screaming at the driver to warn him that his tyres are cold and he should warm them up. Obviously a well warmed up tyre gives better grip and improves performance so it makes sense to have warm tyres at all costs. Still, there is a much more dangerous situation that occurs on cold tyres. A tyre is inflated with a low pressure so that with heat going up, the tyre will be at the optimum pressure. On the other hand a cold tyre will go even lower in pressure and this means the tyre can flex and move a lot. Riding a stepped kerb on a very low tyre, will make it vibrate and flex a lot. This can provoke carcass damage, can make the tyre lose contact with the rim and small amounts of pressure, eventually creating a vicious cycle that can provoke permanent deflation of the tyre and puncture! All of this is now simulated in ACC.​
When the pressure goes under 24psi, you will get a warning from pitradio to keep an eye on it and avoid kerbs. You should really avoid kerbs at all costs when the pressure is so low. If you ride and slide over stepped kerbs with such a low kerb, the tyre might lose pressure. If the pitradio understands that you lost a good amount it will warn you again. It’s up to you of course to do a pitstop and put new tyres or raise the pressures, or risk it and stay out trying to heat up your tyres and raise your pressures. But don’t blame us if over a kerb the tyre will instantly deflate and you’ll end up spinning with no grip… or tyre.​
Go outside the track and rejoining, running wide on grass and sand traps can also provoke similar tyre damage situations. All in all, the more you abuse your tyres when not in correct pressures, the more risk you have to get a puncture or at least to seriously compromise your tyres life.​
A typical scenario of what you might experience: You start with slick tyres and correct pressures. Dynamic weather changes and you get night time cloudy with lower temperature or slight rain. You think you can handle it with slicks and decide to stay out. The grip is not bad but the tyres lose temperature and pressure fast. You get a warning from the pit radio which you ignore and you keep pushing on the kerbs. Another different warning, this time the pit radio says they detect a slow puncture or simply you’re losing pressure. Another kerb, and another and then that frightening sound of a tyre exploding, sparks from the under tray scratching the asphalt and your car spinning without control… maybe you should have made that pitstop for rain tyres.​
Obviously the system is brand new and needs tweaking, so we appreciate your feedback. There is nothing random in the system, all of it depends on your actions, but some of the causes and effects are not predictable. You can never tell how your tyres hit the kerb or what impact they got in the re-entry from the grass, so some effects might seem random to you, but they are not.​
We think it adds extra depth of simulation, realism and decision making while racing.​
Finally with ACC v.0.7 we also activate the classic damage. Aero damage, drag and downforce, suspension bends, and total crash can happen. It’s a good system, fairly simple, does the job. We will try to improve on that too, in the near future.​
Hope you will enjoy.​

so, setups... i try to collect everything i have.

first, some great readings from Aris, some free time is needed.

about aero:

about suspension:

about tyres, brake wear and brake pads:

about the new chassis flex feature:

about ECU maps (good to save it to a .doc file or something, i use it as help because there are big differences between cars):

about tyres, pressures (read post 1-2-3.):

about strategy and pit stops (for SP races mostly but who knows, maybe we'll have limited tyres for MP races too...):

there are some great blogs about some cars (unfortunately not all): Audi R8 (old), Porsche 911 GT3R (old), Ferrari 488, Lambo huracan (non-evo), BMW M6, Bentley (old and new too). very interesting, and tells about the strengths and downsides of a certain car, also some tips for how to set them up:

i don't know if you can read it without signing-in... let me know and i can copy the texts here too.


...and how i used to set the car up. of course it's just my opinion and obviously i'm not that fast in the sim. but in general terms...

1. i used to start with default aggressive setup. for some cars it's too aggressive for my taste, for some cars it's really nice. in general the front engined cars behave more predictable and the aggressive setup is more safe for them. it's easy to run into snap oversteer with mid-engined cars and with Porsche. if too much oversteer at exits, first just increase TC level. TC and ABS levels, ECU maps are depending on track grip level, you can see the gauge in setup menu with that little colored stripe.

2. first it's adviced to play with riding heights. if your rear is too lively, reduce rear height or raise front height. if you experience the car is bouncing on the curbs hardly too, it's better to raise the front. don't change more than 2-3 mm at one time.

3. if still not comfortable, i used to soften the rear springs and/or dampers, maybe little less rear camber. i don't used to change rear wings a lot, maybe only 1 clicks -/+.

4. brake balances are not the best in my opinion, i almost everytime set it a little more to the rear, to help trail braking. but be careful, it's easy to get to the other side. it1s good that you can set it by 0,2-0,3%.

5. start with the basic tyre pressures, but i used to set it a little bit lower. the pressure gauge in setup menu shows the pressure if you start from the pits, it will raise around 2psi after the tyres are warm. if the track is cold or damp, you can easily go up to 27-28 psi in the setup, if the track is hot... then there's not much you can do, you can decrease it a little bit but it will be still warm... operating pressure for dry tyres is around 27,5psi. for wet tyres it's 30-31psi

6. the setup options are working pretty much the same way as in other sims. i mean: springs, cambers, dampers, diff settings, and so on. usually i make front caster higher, it gives better feeling for the front grip for me (can be wheel depending maybe..?) - you can find quite a lot of setup guide, how to handle car behaviour with setups. ride height seems a bit more important here by the way.

7. clean driving is important, it's similar to new R3E GT3 physics. you need to take care about the tyres and your car.

if any question, i'll try to help ;) if something comes yet up, i'll add to this.

Edit #1: wet setup.
the basic wet setup is nice but it's useless in dry conditions. i try to use my comfortable dry setup, with adjusted ECU, TC and ABS levels. it's not bad and it's definitely better than basic wet setup, if you have changing conditions. only thing i'd do is to raise the car in general with like 2-3mm for the wet conditions.

i'm also curious what others hink about setups or the way the cars are behaving.
so anyone has some opinion, let us know!

Hey Robert, will report back with some feedback, doubts etc from a noob. Didnt posted anything mainly because I didnt launch ACC in the few pasts days at all.

But will do my man, will do :)

Maybe this video is also interesting:


Didn't touch setups in ACC yet except chosing default aggressive setup and changing fuel...seems I'm on the right path ;)

Edit: Aris uploaded several videos building a setup and giving some interesting insights:
