I see you get the 6 piston giant front brakes with the package, are the rears staying the same? I was looking through pictures, and you see this nice front brake assembly, but the rears look horribly disproportionate compared to the front... Will the rears be getting upgraded as well?

Horribly disproportionate? The rear brakes do less than 30% of the total braking and thus don't require huge calipers. The rotors however are quite large at 13" compared to 11.8" of the previous S197 models including the GT500(until 2013 where it got 13" rear rotors).

I've seen people complain about the lack of rear Brembo-labeled calipers on the previous Track Package but honestly other than ease of pad replacement they don't actually improve braking performance.

Looking at the spec sheet for the GT the rear brakes will stay the same.. 13in X 25mm vented disk with a single piston floating iron caliper.

They will change though for the EB model from 12.6in X12mm solid disks with a floating aluminum caliper to 13in X 25mm vented disks with a single piston floating iron caliper. (essentially getting the GT rear brakes)

The front generally does 70%+ of braking so they should be larger and have more surface area to stop you quicker.

This is purely a cheap-ass cost saving measure. Only the upcoming GT350 and 500 will get multi-piston rear calipers (and calibration to match, so this is not something that will be able to be easily added later on).
This is not only Ford's cheap and dated thinking, it also reflects the genetic memory of the difficulties in putting a multi-piston caliper on ye olde solid axle, where a parking brake would be an engineering complication.
Braking is not always about the usual nose-down attitude that solid axle Mustangs so readily adopt. The rest of the time it's about balance and having brakes that can be made to work to advantage in the back, just like an IRS where the camber curve and toe change can be used by an experienced driver to balance the car in a turn, is important in a serious turn.
So any idea that there is some proportion that is a fixed rule of physics is incomplete.

Ford can't win either way. While it's easy to immediately throw the "cheap" flag out there, larger rear brake rotors, additional calipers, etc would just be one more mass-adding item for people to bitch and complain about. My god, the 2015 Mustang offers Ø15", six-piston calipers on a GT model, and some are blasting Ford for outfitting "just" a Ø13" rotor in the rear? Before nit-picking the car to death, how about we first see how the new Mustang performs? If one wants a more aesthetically-pleasing rear brake set up, I'm sure the aftermarket will accommodate the market accordingly.

Well said. And if people weren't complaining about the mass added by the larger equipment, they'd gripe because the price of the car went up too much.

Like you said, the aftermarket will accommodate. Or some can simply wait for the SVT model which by all indications will have fancier looking rear brakes, and the requisite increase and price to go along with them.

I've said it before and I'll say it again, we can't expect top-of-the-line parts in every aspect of the car while still maintaining the value that this car represents. Creating a performance bargain requires a lot strategically chosen compromises that when combined, have minimal effect on the overall performance of the car, but DO have a significant impact on its cost... this is an area where Ford has excelled with Mustang, and until I see otherwise, I'm giving them the benefit of the doubt that they have continued that trend with this car.

I personally don't care about the weight and I am not nitpicking the car, I was just questioning the brake setup as I just realized the rears will not be upgraded along with the front from the performance package option I added to my ordered vehicle. I do not know about the technicalities of braking power, but I do realize the front do more braking, and also realize there has to be a certain balance between the two brakes, it just does not make sense to me that the stock setup is the way it is, and then they add much beefier brakes in the front without changing the rears, I feel like that would "offset" the balance if there is one. Again, I do not know. I was just asking.

Very simple. Look at a Camaro. Very large 4-piston Brembos all around.

Just thinking outside the box here, but how 'bout we see how it performs before we pass judgement on Ford's decision making... ;)

The 2014 F1 cars have smaller rear brakes than the 2013 F1 cars; there are many more factors but they felt the weight savings in that area would be more important.

All or nothing...

That is one point I really can't understand from FORD. Upgraded brakes on the PP for the GT with ONLY the front axle set up for 2x BREMBO calipers?? That is cheap. And yes. I know that front brakes doing the most work. Not even 2/4 pistons calipers on the rear axle?
It's a joke. Sorry to say that.:thumbdown:

6 on front, 4 on rear... what's the problem?

It's been proven that having more pistons means absolutely nothing...

The M5 has(had) just a simple dual piston setup for the longest time and still stopped from 60-0mph in 112 feet. The 2014 Mustang did it in 107 feet while weighing 400lbs less than the M5

Quit drinking the koolaid, people...do some research before you judge something very few people have even driven yet... It's almost like the engineers know what they're doing!

According to the Dealer Source Book, rears are single-piston on all trims. But they are at least good sized 13-inch rotors (GT & EB+PP).

People need to remember that a fancy caliper with more pistons in the rear doesn't equate to better braking. One important thing people forget is the tires. The brakes will stop you as fast as the tires let you. If you don't like the single floating caliper in the rear, wait for aftermarket, get better tires or buy a GT350...
