Can someone please explain the "Big Brake" craze that's going on? I'm seeing cars with 14", even 15" rotors, with 4 or 6 piston calipers to match. Why would you ever need that much brake on a street car? Is there an actual performance reason for having such large brakes? I would think that the tire is the limiting factor on any street car braking system, and if I can lock up the tires on my car by standing on the brake, I've exposed the "weak link", so to speak. I can see road racing cars using larger brakes due to fade resistance and having stickier road racing slicks, but it seems overkill for the street(and expensive overkill at that). I can't see making repeated stops, or slowing down as much and as often on the street as you would when road racing. I guess it falls more under the "bling bling" factor, or needing something to fill up those 20" rims that are popular too?
