OK i looked at ford parts and for 2005 gt i got BRRF-42, for 2011 GT 5.0 or 4.6 i got BRRF-19 so i think it is different

 

Yes, 2011 is 5.0 only (even odd-er is how www.fordparts.com had me choose between 3.7, 4.0, 4.6, 5.0, and 5.4 engines when choosing 2011 model year...methinks the website am confused)

 

Hmm, I got BRRF-42 on both...odd. Was the part number 1125 for both on yours?

 

Good news for you! I checked Autozone's website and here's what I found:

2011 GT front rotor
Part number: 42253
Outside diameter: 355MM

2007 GT front rotor
Part number: 42134
Outside diameter: 316MM

One thing to note however, is that the "height" of the rotors is different. 2011 is 46MM, 2007 is 48MM. I also can't tell if this is Brembo or not...dang websites.

EDIT: It does say "performance package" for the 2011, maybe that means brembo? I'm going to find you some answers here...

 

Yes performance package is brembo so I guess good news !

 

I went to http://www.oreillyauto.com and verified what you said here. According to their "compatibility" tab the BRRF-19 is only compatible with 2011 models.

HOWEVER,

I looked at a different brand of rotor and it says this:


I guess we'll find out the real results when you get your new hardware...do keep us updated! If this works out for you this may be in my future plans

 

You sure that's not the REAR brake rotor? Because all the rear rotors are the same.

 

I'm thinking they are saying incompatible because of the increased size the calipers will not work unless they are from 2011 as well

 

Yep I'm sure, I selected "Front" in the options and this is what it gave me:

 

The brakes are coming from Cali to South Carolina so if they get on the ball and ship tomorrow there may be a chance that i get them by weekend. This is going to solve so many mysteries and clear so much confusion, i just can't wait to install them, or try to anyways.
