I was looking at the specs for the 2011 Mustang GT and noticed that the front rotors are now 13.2 inches. My 05 GT has 12.4 inches front rotors. Nowhere does it say in the 2011 that they increase the rotors size (and width).

Was the larger rotors part of the 2010 Track package ?

Here are my references:

2011 GT Specs: http://media.ford.com/images/10031/2...g_GT_Specs.pdf

My next question that comes to mind: Do the pads or calipers have a different P/N or is it just the caliper bracket that is larger in order to fit on the larger rotors.

All of this to know if can reuse my pads/rotors I use on the track as long as I use a 05 caliper bracket.

Anybody know ?

I believe that's new for the 2011 GT. Bigger engine means bigger brakes.....

Not sure about the pads but the larger rotors are going to be standard on 2011 GTs. The 2010 track pack did not have larger rotors, just high performance pads.

As I remember the '10 3.73 Track Pack (II) used the carbon metallic pads specially designed for the 08/09 Bullitt 12.4" front brakes. That was an upgrade over the GT pads and the Bullitt used the GT500 pads on the rear 11.8".

The unique live rear axle uses a tall 3.73:1 gear that helps launch the Bullitt with vigor
• Stock Mustang GT shocks and struts were swapped out for new units that allowed engineers
to dial in a more aggressive driving dynamic while still maintaining outstanding ride and balance
• A tower-to-tower brace, designed specifically for the Bullitt, lends additional torsional and
lateral stiffness to the chassis for improved cornering

• All-new front brake pads were developed specifically for Bullitt while the rear brake pads come from the GT500

The 2010 track pack for the brakes also includes dual piston front calipers

I still haven't read which brake pads and calipers the non-Brembo 2011 GT gets. I'm hoping they are the same quality as the 2010 Track Pack.

I never understood that spec on the Track Pack; the GT has had dual piston calipers for years (at least since the '05)!

Judging from the pics, they look the same as the 05+, just bigger rotors. You never know....

And yes, the GT has had twin piston calipers since at least 1999.

The 3.73 Axle Package on my '10 also has dual piston calipers with high performance pads. No one I've spoken with seems to know if these are the same as on the Track Pack and/or the GT500 and how do they differ from a non-3.73 GT since all GTs have had dual pistons for awhile now?

Since early literature for the '10 referred to the 3.73 Axle Package as Track Pack I, I'm thinking they may be the same as the Track Pack (formerly Track Pack II). I believe Canadian cars are still sold as Track Pack I and II.

It would be nice to know what I'm talking about when people ask me about my ride .

Ya it would nice if they clarified about the dual piston calipers stated in the details section on Build and Spec for the track pack. Seems odd to put it in the details if its the same as it has been for a while.

I think they just listed it as a feature even though it isn't out of the ordinary. The Bullitt has dual piston front calipers also, but the pads were unique. Ford made the point of itemizing both on literature. A number of the Bullitt's features were carried on to the 2010 GT and improved on the Track Pack options. Seems like the magazines detailed this when the 10 was announced.

"The 3.73 axle allows for a more-responsive Mustang, especially at mid-range speeds," Barnes said. "The carbon-fiber plates allow a very robust architecture in terms of temperature and repeated hard driving on the track."

PerformanceŽ Friction brake pads, which better resist brake fade, are used front and rear. Both the anti-lock braking system (ABS) and AdvanceTrac were retuned to complement the advanced capabilities of the new tires and brakes. AdvanceTrac is standard on the 2010 GT coupe and can be operated in any of three modes: On, Off or Sport.

"The Track Pack covers all the bases," Barnes said. "The new tires give the Mustang more grip, we have a more-responsive acceleration, better brake linings that are more consistent over time and the car is tied down better because of the changes to the bars and the shock tuning."

So back to the OP, the larger rotors first appeared on the '11.
