What sets one brake setup apart from another?

Most stock brake systems will lock up the tires. The question is will they still be doing that on lap 30?

Modern caliper design includes little things like changing the angle on the pistons and size of the pistons on the caliper to equalize force on the pad and wear.

Bottom line if your opinion of a good brake is it's ability to lock a tire then you won't have any trouble finding a good set of brakes

^That's kind of the point of the thread; To determine what makes one brake setup better than another.

The StopTech article was very helpful. However, I still don't see a need to drop the better part of 10K on a four wheel brake setup that will doubtably ever be tested.

Speaking of brakes, has anyone released braided brake lines that are known to fit our car yet? I was kinda waiting on those before I swap my fluid out (figure I'll do it all at once).

For a specific car the stopping distance depends mostly on the tyre. Wheel alignment, tyre pressure are factors. Also the further you deviate from the standard set up the harder it is for the ABS to function. The only way you would stand a chance of out stopping an ABS system would require 4 brake pedals and 4 feet to operate it. As the ABS modulates the brake pressure to each wheel individualy in a time cycle way shorter than human reaction times. So alternative pads , race fluid, braided lines and additional cooling air ducting is almost certainly all you need. Unless you are running in a race that does not allow ABS or you wish to change for cosmetic reasons. Contrary to popular belief as has been described above bigger brakes do not stop faster they just lock earlier.
