I say Brembo, but keep in mind that Brembo does not make any cross-drilled and slotted rotors. If it's got both, it's been modified and likely won't be covered under their warranty. This information comes direct from Brembo. I have a good friend here who got the shaft when his Brembos (actual Brembos) began to rust. When they machined them to drill the holes in them, the second party company messed up the anti-corrosive coating from the factory.

Just an FYI. Besides, slotted rotors are more structurally sound. They will wear your pads down sooner, but which is cheaper to replace, ya know?
