brembos dun make slotted discs. they make blanks and another company will cross drill them or make them slotted. and tires are the best for stopping
but if you really want to upgrade brake pads and rotors...i have brembo blanks with EBC greenstuff. i like it but i am going to try out other pads as well. try out axxis ultimates pads or hawk hp+ pads.
