i was under the inpression that slots or vents improved braking because the pad would catch the edge of the slot when it when by thus causing more friction but wearing the pad out a little faster. but idk. atleast you know with all that cooling that your rotors wont warp. some cars probably should have drilled/vented rotors. the stock brakes on our malibu are terrible, they warp within a month of being put on every time. and after searching online it appears to be a common thing.
damnit! cant sleep
