2023 GT Brakes Fixed?!

[Jstang23]

I can't understand what point you're making here, or what question you have.

2023 production is long over at this point.

Actually my GT was made late January of '23... only 1.5 months ago. My point is trying to understand why my car differs from other stock 2018-2022 GTs.

It wouldn't.

Since you're focused on road-course stuff, I'm shocked you didn't get the Performance Pack 1 or 2. The brakes, suspension and cooling are definitely better.

Are you planning on replacing all of that anyway?

Wow. Did you even read the first post lol. The brake rotors are clearly different. I also understand the performance pack is better, just not worth the 6700 dollars they were asking for it.

Also I remember you from another thread that you spent trolling everyone, so not to be rude but if your not going to read/ actually try to help can you just not respond lol!

Of course I read your first post.

Unless you're going to post pictures of the differences you've attempted to describe, it impossible to follow what you're talking about. No one here has ever complained about their brakes, so it's not a topic that's been covered before this thread. It's not like a "known" issue.

Also, I don't troll anyone. I focus on being technically correct, and facts over emotion. Some people here don't like that because they're too emotionally wrapped up in their car.

For instance....this thread title of "2023 GT Brakes Fixed?!". That makes no sense, there's been no issue with them AKAIK. You're acting like there's known issues plaguing Mustang brakes, but that's not true.

Hey all, I recently picked up a 2023 GT...

First: The front brake rotors have been corrected. Previously the vents were facing the outside causing the cooling ducts under the car to basically not cool the brakes.

...And adding cooling ducts to stock brakes would have been fairly useless, since you couldn't get the air to go through the vanes of the disk.

That was a big part of why I bought a Performance Pack car.

I'm just wondering if anyone thinks they might have changed things, and not told anyone. With the new s650 coming out soon I bet Ford is trying to empty the parts bins for the s550... wondering if they have put any parts from the higher models to improve things a bit for the final production year. Just looking for possible opinions on this and since the rotors have been flipped would anyone still recommend changing the brakes/fluid for a track day?

Thanks!

Ford could have easily made changes without announcing it.
If you had higher end parts from other Mustang trims, you might be able to answer some of that yourself:
After the "inverted hat" GT brakes the next option up was the Brembo brakes on the GT-PP (Right?) If you have that, and if they left off the Brembo logo, there should still be signs such as a 19" wheel. I don't think OEM 18" wheels could fit over the OEM PP1 brake caliper.

If you've had your car on a lift you should be able to see if it has a diff cooler or extra oil cooler.

If you don't have GT-PP brakes or an add-on diff cooler, then my next question would be:
Did some 2023 Mustangs get some early S650 parts, before the rest of the S650 started production?

Some Mustang owners have known for years that the standard GT brakes have a terrible design for cooling (and wouldn't stand a chance on track). It stands to reason that Ford would improve on them for the S650.

Wherever you are (Northern Georgia?) it's winter there, not much warmer than where I am, and I wouldn't have expected anything to overheat.

Even on a track in summer, you weren't guaranteed to overheat your differential in the first place. It happened to some owners and not others.

When I first got my Mustang I asked my mechanic - who has maintained a Mustang track car of his own, and those of several customers - if I should get a diff cooler before going to a track.
Rather than jump at the chance to go "Yes, I can install a diff cooler for you [at my usual hourly rate]" he said "Don't worry about it."

...But he said OEM brakes, even the larger Brembos, weren't up to running laps. I would need some other pad compound to take the heat of a 20-minute lap session.

Most owners won't overheat them, but the standard GT brakes are an absurd, bass-ackward shape.

Hey all, I recently picked up a 2023 GT (new from the dealer) and I'm panning on getting into a few (1-3) HPDEs a year with it. I have spent the greater part of the month reading a much as I can about these cars and how they handle the track. I've come to the conclusion that managing heat (brakes, transmission, diff, and engine) is the key to success. I have noticed a few things for the 2023 MY that differs from the rest of the 2018+ models.

First: The front brake rotors have been corrected. Previously the vents were facing the outside causing the cooling ducts under the car to basically not cool the brakes. The rotors on the '23 are now facing the inside of the car. I haven't been able to overheat the brakes up in the mountains yet, I'm wondering how they'll hold up on the track.

Second: The engine/transmission stays remarkably cool. I haven't tracked it but I have taken it to the mountains and to autocross and not once did it ever get hot. For y'alls awareness I did spec miata for a few years so, yes I know that I was actually pushing the car hard for mountain roads. I'm not sure if they changed something... or just because now the engine says to run 5w-30 on the cap now.

Third: The rear diff... also does not overheat. I run an autocross for my area and have taken it to two events now. I put in 4 back to back runs hard driving to see what it would do and it seems like the car handled the heat perfectly. I do not have the diff temperature gauge in my car but I never got the warning. Also my CHT never got above 210.

I'm just wondering if anyone thinks they might have changed things, and not told anyone. With the new s650 coming out soon I bet Ford is trying to empty the parts bins for the s550... wondering if they have put any parts from the higher models to improve things a bit for the final production year. Just looking for possible opinions on this and since the rotors have been flipped would anyone still recommend changing the brakes/fluid for a track day?

Thanks!

* This thread should be in the Road Course / Track section *
(There's not enough love in that section anymore anyway.)

I love that you are going to take your Mustang to the track! More people should.

Couple thoughts / input:
1. If the rotors are corrected now, just try out your brakes as-is and see how they do. Track pads are still a must though. OEM pads can't handle track abuse.

2. I don't mean to sound rude, but if your CHT never went over 210, then you were not pushing the car hard; but that's to be expected on the street. No street scenario will ever accurately mimic track conditions. I've done mountain runs too and temps don't get anywhere close to track levels.
As you build speed, cooling issues will slowly show their ugly faces. That being said, don't rush into cooling mods. Address them as they come up.

Feel free to message me if you have any questions.

Interesting about the brake rotors! Are they still the same size as the ‘15-22 rotors?

the rotors were fixed circa March 2021. It is interesting that the arms now have the vanes on them. I can't say when THAT started showing up...

But you definitely owe us some pics of the arms, of your undertray, of the inside face of the knuckle area.

Can confirm. I have a late build 2021 that came with the corrected rotors. I have air vanes on my control arms, but only because I bought them from FP. This thread reminds me, I need to finish up my air flow project...

What do the "fixed" rotors look like?

What do the "fixed" rotors look like?

If you look at your rotors from the outside of the wheel and :

You can see both ends of the vanes (like the rears) = Bad.

You can only see the vane ends around the outer diameter of the disk = Good.

That's just Vorshlag marketing.

Telling people something is wrong, and they have the answer to fix it. Just pay the money.
