big brakes, why not the 2012 Stang GT

I have stock manual disks in front, explorer rear disks and will say that although they will lock up the 245's in the front, they get blue from even the slightest spirited driving and I'm guessing will suffer a nuclear meltdown during an autocross.
Repeatable stopping power is needed and I think this is where we're going with this thread. With bigger rims and tires, we're overrunning the capabilities of the stock disks to perform well repeatedly.
I'd trust my brakes at the drag strip and in normal traffic, but not at the autocross.

I'm interested to see where the conversation goes as I'll be looking for a solution soon as well.
