GT and GTPE brakes are NOT the same?

[SnBGC]

The issue is the marketing clearly states that the GT & GTPE have the same size rotors, the current parts guide has the GT using the same rotors as the regular mach-e, as there is only 1 dust shield which is made to accommodate both, the GTPE rotors have a few mm to spare where the normal rotors have a more obvious gap, the photo posted of the GT has that same gap which matches parts but goes against the marketing.

Hence the op wanting clarification and quite rightly expecting to get what has been marketed not a switch a roo, as false advertising tends not to get looked on kindly legally so Ford need to offer an explanation.

Okay thanks.
So, it sounds like the OP doesn't have a car to measure for himself yet?

And it sounds like someone has confirmed the dust shield is the same for all models?

And nobody has looked at the rear rotors of a GT yet?

If the GT has the same front brakes as the other non-PE models then doesn't it also make sense it would also have the same rear brakes as the other non-PE models? Wouldn't that be super easy to see with a visual check?

The literature says the GT and GTPE have same size rotors front and rear. Has anyone posted photos of the front and rear wheels from a GT? That would be a good clue right there because it would be easy to check.

As far as I can tell.....there is no version of 18" rear rotors on any model so if the GT has the same size rotors front and rear (which can be easily determined by visual comparison) then they would almost certainly have the 19" rotors.

Or of course just pull the wheels and measure the damn things but apparently that hasn't happened yet. If I had a GT or a GTPE available to me then I could answer the OP's question fairly quick.

They really need an eye roll emoji in the "like" list for all the people who just haven't taken the time to read and keep repeating the same thing over and over.

I've often reached over to give posts the eyeroll reaction and then I remember there isn't one and then I'm thankful because if there was an eyeroll then it would be very difficult to see any of the other reactions on this forum. <sigh> ?

There's no 19" rotor or 18" rotors on any Mach e and the GT does not have the same rotors front and rear.

Jesus Christ everyone stop referring to that stupid marketing material like it means ANYTHING it's all completely wrong and we've known it since day one.

Ok guys...check me here. The GT brakes sure look to me to be the same size as the premium when seeing the caliper clearance and how much heat shield is visible versus the GTPE.

This is pretty messed up if so as all the specs indicated the GTPE brakes are the same as the GT.

Can a GT and GTPE owner go measure their rotors to confirm?

There's no angle where I can get my GTPE to look like that GT disc/shield. Even at extreme angles all you see with the GTPE is the lip of the heat shield barely peeking out, not 1 cm or more of the sheild past the lip. It really does look like that GT has smaller discs.

If I read the technical documents correctly. It appears the Select, CR1 and Premiums (including FE) have 18" rotors front and 17" rear.

GT and GTPE show as having 19" rotors front and rear.

Someone at Ford clearly cannot do math. The spec on the GT and GT-PE front rotor is 385mm OD. That is 15.16”. Assuming the marketing monkey (am I racist for saying that about someone in marketing?) made similar mistakes on the non-GT models, they would have ~14” rotors in front.

I do not have a car yet, but it seems a pretty simple matter to remove a rotor to measure the OD or to simply use a tailor’s tape to measure the rotor circumference and divide by pi to get the OD. We just need an owner of a GT and an owner of a GT-PE to measure, to put to bed the argument about GT vs. GT-PE rotors, then an owner of a non-GT to do same.

Yeah, the parallax from a photo through the wheels is going to make things look wonky. Don’t rely on that at all. Direct measurements is what this thread needs. Anything else is conjecture.

use a tailor’s tape to measure the rotor circumference

I thought about doing that yesterday but not until after I already had the wheel back on. I'll do it if we manage to get someone with a GT to do it.

Can just use a string if you don't have a tailor's tape.

Here's a better pic I stole from the aftermarket wheel thread of a GT.

Yep. Just use the strin to get the circumference and then measure the string. ?

Here's my GTPE. No amount of parallax is gonna cause this much difference IMO.

This has now become the 1/4 mile track results post of brake threads, only 70+ pages of comments to go ?

That said, Ford/Brembo Marketing/Comms have some real problems with their press releases and spec. sheets.

1. Falsely/mistakenly stating GTPE and GT rotors/calipers are the same.

2. Printing info. about 17”-19” rotor sizes is just preposterous. There are few road cars in the world that utilize rotors larger than 16”+ and all are behemoths or exotics, or exotic behemoths. 18 and 19” rotors are practically unheard of. Plus, it’s even worse when they’re printing that for cars with 18-20” wheels. There would be no clearance for calipers. We’d need 21-23” wheels.
