Remember though your brakes are only as good as your tires. People think they need bigger brakes even though they were locking up their tires with the stock package.

Getting better tires (think of it, what else is connected to the ground?) will slow your car much better than a big brake package.

With my last setup I could lock up my brakes, which meant my tire grip was lacking. I upgraded to Azenis and now I can barely lock up my car, but I can sure stop faster and shorter.
