Yes, if you plan on tracking the car you can upgrade the pads to something more track worthy. I'd be willing to bet that in the lighter GT, the brakes will hold up quite well on the track.

 

Depends on a few things. Brake fluid, pad compound, rotor size/design. Those all make up for impacting the braking abilities of the vehicle.

I'd guess the 19" Brembo GT comes in around 3750 with some options on it.

 

What's wrong with OEM caliber? A lot of OEM's use Brembo calipers from the factory.

The problem isn't the braking system, it's the pads. Ford puts pads on that have to meet NVH requirements. If you put a decent Hawk, Carbotech, or Performance Friction pad on the car it will hold up very well. Hell, there are guys that do very well at open track days with minor upgrades to the stock 2005-2010 GT brakes.

 

It's not the calipers, but the rotors that can improve. A good slotted rotor with a track compound pad will work wonders. Sure, they won't last, but they'll bite hard.

 

Yeah. People seem to think the GT500's total weight comes from the iron block. Nope. GT500's are essentially loaded from the factory with few available additional options. Factory 19's, brembos, 6 speed etc. Then the blower and intercooler system adds quite a bit of weight.

People here will throw a blower on their 2011 with 19s and brembos and say " it weighs 3603 lbs "

LOL

Yes, some people don't realize the complete effects of modding a vehicle. You gotta look at the total package to make sure everything works in conjunction with one another.

 

I understood....You are trying to discredit the GT500's braking system since it's a factory OEM system. I guess a lot of OEM manufacturers are dumb for using Brembo as their OEM choice.

Like I said, the GT500's brakes fade due to WEIGHT.

 

Wrong. Completely. Ever driven one? Ever modded one?

 

How many track days have you driven your GT500 in bone stock?

I can point you to various track tests where fade was mentioned. But if you have never been to a road course, you don't know what real fade is so I can understand your post above.

 

3.

A 3700 lb GT will fade in the same manner. Or are you still locked on a GT with 19's and Brembos weighing 3603? They'd fade after 1 additional hard grab on a 3200 lb car.

 

Here is what you do not understand. Brake fade can be effectively by removed by A. Pad selection and B. Rotor cooling/ducting.

The GT500's calipers and rotors are perfectly fine. The pads that Ford chooses for the GT500 are a comprimise from the factory (NVH requirements)

Additionally, how do you know the 2011 GT will weigh 3700 lbs with 19's and the Brembo option? Who knows, maybe that 3602 # has that factored in since the 2011 gained 70 lbs over the 2010.

What I find funny is you comparing a 3900 lbs car to a 3200 lbs car. After that comment, I think you should brush up on braking physics:

Yes a 275 tire will fit fine on a 9" wide rim but optimal would be 9.5". I had a 98 Mustang SVT that was running 17X9 Cobra Rs with 275's on the car. The sidewall would get better support with a 9.5" wide rim for a 275 tire. A 255 tire on a 9" rim is actually optimal, I wish Ford would have given us a 9.5" wide wheel. Either way still a major improvement over what is offered now for the 2010 Must GT. They are putting 255's on a 8.5" rim with the TrackPack now.

I know several people who have tracked their GT500's and didn't have any issues with fade unless they were running R compound tires. They are running different pads, fluid and front ducting cooling.

The stock Brembo calipers are fine, I would just maybe try and upgrade the rotors. Another issue is the fact they aren't floating rotors so the heat gets transferred to the wheel bearings.

Very true. Heck, I'd even say that the current 285s on the GT500's rear 9.5" rims, while they do work, are less than ideal.

 

Very true as well, the minimum rim requirement for a 285 is 9.5" while 10-10.5" would be optimal. I ran 285/30's on a 2004 BMW M3 with a 19X10" wheel..it was perfect.

Here is my old M3 with a 19X9 and 19X10 RAC Monolite RG4's with a 255/285 setup.



The sidewall was supported much better.
