Carbon brakes don't increase stopping power compared to steel. They stop exactly the same. The benefits to carbon are their ability to fight fade. You are correct that, in most cases in GT7, you're not going to see an advantage until we start getting endurance races.

I hope in a update they add the squeal of cold carbon brakes and after a few laps stop squealing. Also with more endurance races coming in the future, they'll add that carbon brakes don't fade after 20-30 laps and the slotted racing steel brake do. I think it would make the game even more realistic, without compromising the fun of it.

I’m still in awe as to how insanely good the photo mode is. If you showed anyone that picture of the brakes and tire set up, even at full exposure, I guarantee they’d think that was a real photo.

A few points I wanted to cover that others have mentioned: -These results make perfect sense! Increased stopping power isn't the point of carbon brakes. The primary purpose is to reduce brake fade, which I discuss briefly at 6:46. -The braking force bar does not show the white bar in replay mode, which is where the race brake runs were captured. In normal gameplay, the white bars reach the same point and are modulated the same amount by ABS. The red bar is your input, and those are also the same here. -ABS off should not make a difference here, and testing without it introduces another variable to the experiment, that being the level of consistency a human can achieve with unassisted braking. ABS interferes at the same exact point with both brake discs, so it stands to reason that the same amount of braking force is achieved. -This test holds true even on racing soft tires. -This test holds true even after running multiple laps in an attempt to warm up the carbon brakes. If temperature was simulated accurately, the carbon brakes would perform a bit worse at the start and start to perform better as they warmed up. If you have concrete proof/testing that shows brake fade exists in the game, please share so we can learn together! If you leave a comment about a point that has already been addressed here, it will be deleted.

Very in depth review. Appreciate your upload 🙏

I just started building my dream TransAM last night and sat there debating on whether or not to get the carbon breaks can suspected there was no difference. I end up going with the carbon but glad I know this going forward. It was the first time I went with them and the last until they update something with them. Thanks for a great informative video.

Another top quality video! Modern real carbon brakes and pad materials don’t have some of the cold use/squeal issues of the earlier ones and the ABS factors in carbon brake temps AFAIK

Appreciate the time and effort you put in to the video's and this information does help out newbie's like myself so a big thanks and support for you 👍

Thanks for testing, have never decided to buy carbon brakes yet but if they're not reducing the car's weight and in this case any un-sprung weight (that of which the car's suspension springs don't support which is the primary reason for alloy / magnesium wheels and callipers etc etc - which I presume don't reduce overall weight either) it's a bit of a shame and presumably a gimmick at this time. Perhaps it will help in regards to brake fade in the longer 24hr races once these're included.

I've found that carbon brakes are snappier in feel when on the limit, whereas steel are more progressive. Could just driver preference.

like the videos, keep em coming. havnt played a gt game since gt6 so all thos info is needed

I was wondering about this. Thank you 🙏

Another great vid!! and OMG it was way above and beyond identifying the ghosts like that ....and to get out and walk to breaks to check LOL... that cracked me up.. top notch stuff there.

You must cover the differential next. I've seen some good tuning guides on them but I'm sure your detailed explanation will be gold.

Subscribed, I really like your endurance tutorial, that was fantastic info

GT has never had a upgrades effect weight. If I were to put a turbo on a base model civic. The manifold, turbo, oil lines,after cooler, piping. All this kit would add weight, while it will depend on the set up. It could add from 5kg to 25kg easy. Changing Exhaust would reduce weight Changing rims would reduce weight most of the time(depends on size of stock to what youre going to) While adding some of this can be tricky as each turbo kit has its own weight for each car. as does the exhaust kit. Rims is a point where they can easily get the data from the rim companys website as its listed. But knowing how much the stock weight is harder to do.

Thank you for the heads up brother! I wonder what other parts are not worth buying!

Thanks for the experiment, bud!

I’m new to GT7 or GT in general and I just wanna say your videos are perfect for learning all the little ins and outs of the game. Plus you put it in a way that’s easy to understand and apply. Keep up the good work! (I also liked and commented for algorithm purposes, more people should see your content)

I assumed there was no difference when I saw the pp was unaffected.

Very interesting, thanks!

Thanks for this video 😊

Preciate ya brother!!!! Had this question as soon as i saw the whole braking situation haha

Thanks for the tip!

Thank you for this Great videos

GT7 does not simulate brake fade in any way in physics model, so unless they add that in an update, there still won't be a difference between the two even in endurance races. however just given the fact that they gave us the option, i'd say it's pretty likely we will see brake fade and heat build up at some point in an update.

Even the game mention this Racing/Carbon brakes perform the exact same way. All 3 of these allow color calipers. However, the carbon brakes just have a different darker disc, so your paying extra for the material look (I.E Cosmetic). As Harmonic explains There would be extra PP points if there was performance benefits and there would some in-game mechanic showing brake tempts/degradation over time. So yes there are IRL implications but this is still a game. Otherwise, there would be more shilling for parts that cheese the mechanics, imagine if there were certain wheels in the shop that were lighter then the rest. Or those nice 20-inch wheels you like the look of would essentially sandbagged you in the race. People hate tuning as it it lol

I think with the upcoming update and addition of endurance races, the carbon brakes will maybe have more practical purpose.

Great explanation

4:50 lol I like the idea of taking pictures of other cars to get a rough idea of their setups. this also works with Ride Height for Grid Starts :D

Omg thanks for breaking that down in the game & real life!

I ran just 2 laps in nurburgring with a tuned up and turbocharged porsche 911. I was getting heavy fade. By the end of lap one I had to back off a smidge. But I got my brakes back after the strait. I could immediately feel the difference. Then I watched the replay and it was a night race, my brakes were glowing bright red practically the whole race. A light bulb went on in my head. Never even considered it. But that's gotta be the deal with ceramics. Also why, all things being equal, somethings still don't work the same way twice. Very cool!

Huh I always bought the carbon brakes similar to what you said at the start of the vid I always thought they would perform better thanks for making this I'll be saving a lot of credits now with this info :)

I believe you are at the mercy of tire grip and ABS is kicking in because of the tire. Redo it with a RS tire.... Thanks for the content.

great video!

Thanks! I was wondering the same thing. Thanks for proving it's no better. I'll save my credits for better items. 👍😎

this channel is awesome.

Nice thanks man

I would be very shocked if someone tested endurance performance and found that there is brake fade in the game. Maybe higher load applications, aka LMP1 lemans scenario where you're braking very hard repeatably would see an advantage to the carbon brakes if brake temps are a thing in the simulation.

Thanks heaps for this, carbon brakes may as well be a GT auto item

Thank you!

Nice video, can you to a heavy brake test on special stage ? Where you brake like 5 or 10 times going 200kmh (or the mph equivalent) Breaking, accelerating, braking etc. for 5 or 10 time. I think at this test we should see a difference

On your way to 100k

Thanks bro.

Good to test it, but... Polyphony could patch it at some point, and if I happen to miss the notes of just that happening and I run with lesser brakes and think they are the same, well... To me personally it's not that big of a difference in credits that it concerns me. If I am to fully upgrade a car I will choose the ceramic brakes. If it's upgrades just to pass one test, then sure, I'll cut down on the expenses.

Great test. Are the tires the limiting factor here? I.e. if you don't have racing soft tires, does the capacity of the steel drilled rotors exceed the tire capability so it doesn't make a difference anyway?

All this time I been wasting money on carbon brakes , glad I saw this thank you my friend.

thanks boss i think ima still go carbon for ocd's sake

Thank you

I know i'm late to the party, but I noticed you were using Sport Hard tires, is it possible you are hitting the limit of the tire grip available for braking with either rotor on those tires? I would be curious if running say Racing Softs makes any difference.

I would like to share my experience with this subject as a relatively slow SIM racer. I was always in the top 10% of all GT7 drivers on lap time, but also always far at the back of my group of SIM racing community...by seconds a lap. I watched a few videos by some relatively talented SIM racers also saying carbon brakes were a waste of money. Their lap times were either unaffected or slower with carbon brake discs. The problem is, they are really good at getting their braking right. What I found with carbon brakes is that if you fluff your braking, carbon brake discs allow you to keep braking for longer into a corner without fade, thus allowing you to slow enough to get around the corner. But they achieve this without much of a penalty during the 1st phase of braking. So what I do, is buy only the carbon brakes and not "waste money" on any other type of brake disc.... So if you are not perfect-like the majority of SIM YT streamers are...(and by "perfect" I mean in the sense that y Ex-wife called herself "not perfect" to justify her terrible behaviour...regardless what she actually did...😐)...I would go straight for carbon brakes and skip the drilled or grooved/scored/slotted brakes as a waste of money.

What is the strategy for the Infiniti 1,000,000 concept what I do with it thanks

U know some thing, I thought this was the case, I installed drilled brakes on a 911 turbo, didn't have the money for carbon brakes at the time, after a few races got the money for the carbons, I installed them expecting to take a few seconds of my lap times, instead I felt like I had to go back and make sure I put the carbons on, as I felt it was no difference in stopping power, thus vid has now shown me that iam not mad and in fact there is no difference in the 2 brake set up, thanks my man for the vid, tumbs up and a new subscriber 👍😊

Then there's racing brake pads have they any better effect?

Carbon ceramic’s big thing is the lack of fade, I thought. Not just one corner or 1 lap but but long distance

It does say in the description of the brakes: "Not a bad way to jazz up your car either!" so they are probably just for looks (at least for now)

Liking/commenting on another good vid

You should do a fully setup on iconic cars for handling and speed

There seems to be more "bite" in the carbon vs the racing. I been using the Viper (all of 'em work well for this test) since is has insanely large front tires and a lot of mechanical grip, which is turn has allowed me to really make good notes on modulation depth. I'm not sure if they need to "come up to temp" because the tires also need to come up to temp as it were, can't tell personally.

Thanks

The credits aren’t a big deal but the PP points are! I’ll be using the slotted or drilled from now on.

I noticed awhile back the PP didn’t change at all between the two. So I was like funk that noise I’m not paying extra for the same performance

I appreciate you testing the things I think about but am too lazy to test. One thought is stopping force may be limited by tire grip before you are seeing any difference in the brakes. Clearly not worth it for sports tires but that may change on a racing tire. Just a thought.

The big problem is that more stopping power is useless if the tires can't follow, as they become the limiting factor. Basically, if your tires can lock up in a straight line by slamming the breaks, you already have more than enough stopping power and anything beyond that will just make it easier to lock up and will make breaking less precise.

Has it been tested to see if adding the wide body makes a performance difference? I know that it SHOULD be beneficial, as you also are able to fit wider tires, but I haven’t seen any info about it yet. Just like the carbon ceramics SHOULD perform a bit differently, I’m curious about the wide body I have at least tested the down force add ons and those have made a pretty good difference, especially at higher speeds like it oughta make

This game os definitely not friendly to beginners and as a pure automotive and motorsport enthusiast I absolutely can't get enough of this!

😲😦interesting

Think it would be great if your brake pads had actual wear much like the engine oil etc and that they need replacing accordingly

What about high end supercars with and without the race brake pads. I know alot of these cars already come with some form of carbon rotors. Curious if it's possible to make brakes worse by changing the pads.

Do the brake pad upgrade make any difference? Also, would have been good to see the stock discs vs upgrade too

Subbed

As you said the main benefit of the carbon brakes in real life is the lack of brake fade, they actually have less bite than steel brakes when cold. Also the limit of the braking distance with street tires is always going to be the grip, even the normal road car brakes have more than enough bite to lock up the tires.

This is interesting. Have you tried to heat up the breaks and then compare it? or try it in wet weather conditions.

Worth the paint change

I’m really hoping that eventually they start simulating brake fade, it should have been a feature since the ps3 games

its just for the looks! 😋

I had trouble with drilled brakes failing using racing cars and worked way better with carbon brakes. The don’t stop better, they fail less with long braking turns after high speeds straights…

Depends if GranTurismo simulates brake fade. Because carbon ceramic brake would stay cooler and not overheat as much as the normal racing brakes. Or actually watch a replay at night and see if the carbon ceramic brakes turn redhot like the other brakes ?

Thanks for doing this... I wasted a lot of $ getting the carbon brakes

how do we know that these brakes are all about stopping distances? with the carbon brakes I would think that it would have more to do with brake fade or overheating when used a lot. maybe these brakes don't fade as easily with a lot of quick stops

It could be for heat, so if you are doing tons of braking on corners one after another, maybe then it comes into play? Did you test that?

Good to know. Anyway, how to get the F40? With a lucky ticket?

I wish somebody could check the programming and give us the actual specs on upgrades, drag, and traction, track limits etc. i know in grand theft auto they have all the specs on downforce , traction loss etc. for each vehicle and the corresponding mod.

I have no idea how truthful this is but I find the carbon discs act the same for a couple of corner but they shine in multiple hard braking zones throughout the race for example the Nurburgring gp circuit I find they get better as the race goes on and there’s more heat in them could be a placebo but just my thought

How do you see your friends rankings is what I want to know

The difference should be repeatability and performance/fade reduction while braking hard repeated times. In my mind it should be: Slotted--->Drilled--->Ceramic however I don´t know if brake heat is simulated in GT7 What makes a car brake better are better quality pads, higher brake pressure (more pistons in the calipers for ex.) or bigger disc brake diameter.

Challenge idea... Is it possible to get a road car as good as the race car variant... With the correct modifications and set up?

What's the best brakes to buy on a car, I find that when I upgrade it they start to lock up a lot more (I play with abs off)?

You should also do an acceleration test because it’s less rotating mass.

Is there much difference in headlight brightness with the different headlight bulbs you can buy? Just subbed and liked btw 😎👍

exactly the same, just like how wider wheels and tires are… exactly the same i guess it also makes sense when your tires never need heated up either and you never have brake fade

Carbon brakes fuck tho. Wish they'd squeal when cold. Thanks for showing there's no difference in performance 👌🏻

GG

I assumed it was purely cosmetic because your PP doesn't increase when you fit them

According to the fact that PP doesn’t change, I just assumed there was no difference. Not much difference in real life except for decreasing brake fade in a long race. That being said I have them on my real life car and they’re great! Definitely seem to lose stopping power in the wet though compared to steel.

I thought they were just cosmetic, since picking them over the slotted or drilled ones didnt add any performance points.

Did you change the pads also?

Great video but I need some help. So I bought the dodge tomahawk vgt and I cant use it because of the pp and I was wondering if there’s any way to lower the pp enough so I can do some races?

I think that carbon brakes are worth for cars that are heavy, even after the weight reduction. For example, if you reach stage 3 weight reduction on the Ferrari 308 and fully tune it, I only put new brake pads, feels great. The disc is original, it brakes just fine. I want to test if I put better discs, if it breaks lightning fast. The fade part is the only reason i think that there is carbon brakes option. But I haven't tested it yet. :( nice vid

Stage 3 weight reduction on a 71 mustang lowered my performance points by over 100
