^^^yes my brother and his friends with 350z's, M3 ,etc have been telling me to. So far i have been reasearching via the computer and forums. But i definately will look for the books you said. thanks!
Cross drilled removes mass from the rotor, mass is good. The more material there is the better it can sink heat away. Removing that material while it looks good and may seem like a good idea is the perfect starting point for stress fractures/cracks. Swap them out for the slotted then when those are done buy Brembo blanks from TireRack.
Cross drilled rotors are for blingy street cars, not for use on track cars.
