Cross-drilled or slotted rotors on the other hand do "vent" brake pad gasses, but even that is overrated. The best benefit of either of those types of rotors is that they constantly "refresh" the brake pad surface by skimming off its top layer. However they come at a higher price and typically much shorter life...

awww, Larry, I know you knew that!
the 126 vented rotors are much better for long stopping, and extended use. like said above, it's the crossdrilled, or slotted rotors that are a looks kinda thing.
them vents, help give you longer stopping before the fluid boils in the calipers! no improvement in stopping force though.
