[QUOTE="2wenty6, post: 513229, member: 20205"] I'll try not to be snarky here, but I think manufacturers have more foresight than that. Designing of the braking system isn't just a bunch of engineers sitting around drinking beer and doing calculations on their computers. The only reason I'm posting is because if there is one system on the car you don't wanna fool around with it will be your brakes, so other members who stumbled upon this thread will at least have an idea of the misconception you're spewing. The [U]fact[/U] is this, having holes affect the structural integrity of the rotors. Especially so if it is drilled, because drilling will introduce micro cracks and create stress points. How is it different from reputable brands selling drilled rotors you ask? Those holes are actually cast during the manufacturing process. It isn't drilled AFTER the rotor is produced - which eliminates the micro cracks and stress points introduced when drilling. If cross-drilled rotors are so good, why doesn't the M cars come equipped with them. Too expensive? The floating rotors themselves aren't cheap. Why aren't F1 cars equipped with cross-drilled rotors? I hope you don't feel that this is directed towards you personally, it just happened that you raised this point and I hope others could make an educated choice if they were to refer to this thread. Our forum isn't exactly a gold mine of technical information so I'm just doing my part to contribute. At the end of the day, it really doesn't bother me if someone is adamant about drilling their rotors, be it new blanks or used rotors. It is their car, their money, their family's lives that they're jeopardizing. If you can afford an X6 you can afford better brakes (if need be). But my opinion stands, there are many things that can be done before resorting to modifying your rotors - and even then, the rotors shouldn't be drilled. I'm just a guy from the internet, do what makes you sleep better at night. :top: [/QUOTE]
