If you say so, all I know is that there's a stupid old asian lady somewhere in Honolulu right now that is still alive to ponder her mortality because I was able to stop VERY quickly after she decided she wanted to go across the street without considering that there may be an element of danger in doing so without looking. In the same-case scenario with my stock brakes, she would have been a smear on the tarmac.
Its not the drills or slots that stop you, its the clamping force of the calipers. I'll take four pistons over one all day long!
