Brembo OEM blanks from Tire Rack (or anywhere else) is all you need for a rotor. More important is to get brake ducts installed... that is the key to preventing brake fade and increasing longevity of pads and rotors.

As stated, drilled rotors will crack. Enough said.

Do enough track events and you will come to understand that rotors are disposable items, the same as pads, oil and gasoline. They are a cost of doing a track event.
