To get the basic jist of it, look to the top, where no cost is spared. That's where you'll get the zero-compromise equipment, or what's best. Not for the money, not for reliability, but for pure performance.

Umm not quite, Ferrari has themselves stated that they use x-drilled rotors for appearance, if that wasn't the case, then why does the Challenge edition of the 360 Modena come with SLOTTED rotors verses the x-drilled all other Modenas come with?
If x-drilled rotors are banned from motorsports events, it's because they aren't safe, not because they are better. Plain and simple, they WILL crack under hard and sever duty use, that's a proven fact almost any rotor manufacture will tell you, even the ones that make them. Look at any racing division (meaning NASCAR, IRL, SCCA, etc...) and if they don't use smooth faced blank rotors, then they use slotted, but never x-drilled. If I'm incorrect on this, point me to something that shows/says otherwise.
