Couple things I picked up from my autox/road racing days.
Cross drilled and slotted rotors are to help with off gassing from brake pads.
Stay away from crossed drilled rotors unless you like rotors that crack very fast.
Slotted rotors are a better then crossed drilled rotors about not cracking.
Both types will eat pads at a slightly higher rate than regular rotors.
You need quality rotors! Don't buy cheap crap.
You can prevent the need for crossed drilled or slotted rotors by buying performance brake pads. Hawk, EBC, Black magic, Carbotech. There are other brands but you get the point.
Last but not least buy brake fluid with a much higher boiling point than normal. Your brake system is a couple pieces of metal using friction (that produces HEAT) to stop your automobile.
Maintenance, Maintenance, Maintenance.
