I read an article in Dsport mag, written by Dave Coleman. He explains brakes, and how you augment them to what to expect. I'ld have to hunt down my magazine to give you specifics, but basically it should improve the amount of caliper to pad ratio. OEM we have only one piston caliper so many mm wide, and this has four smaller pistons increasing the total diameter of the piston. I would have to read over that again to give you all the in and out. Like I said, it's an article in Dsport by Dave Coleman called "Brakes 201".

I use this site a lot for getting a general idea of stuff.

The article I was talking about earlier is more detailed, but I don't have it with me. I'll see if I can find it when I get home. It's from May.
