Drilled and slotted rotors are really overrated and they provide no functionality these days because of modern braking systems. They used em in the olden days cause people brakes would always overheat.
The pulsating in the pedal could just be your superb braking as opposed to what your car was like stock. Does it pulsate all the time, or just under hard braking?
As far as aem pads go I dont know much about em, but a friend of mine with a 97 GSR had to replace his and ended up putting in some other brands of pads cause the aem's wore out within 2 months.
Good luck with all that.
And save some capital letters for the rest of us:finger:
