Pretty sure the 2011+ take offs offer larger rotors but use the same calipers/pads as our cars (though the larger rotor does improve braking a bit and stays cooler).
You can also use GT500 take offs to get improved rotors/calipers/pads/etc.
In either case you will need new wheels if you have factory 17s, and I'm not sure if the factory 18s clear the larger brakes either.
