Cross drilled rotors are for bling only. Do not attempt to road race with them, repeated high speed stops will overheat the rotors and cause stress cracks.
Most people recommend using stock rotors, because you won't see much improvement from slotted, at least for most applications. You would be better served to get SS brake lines and some good fluid, along with the hawk pads.
stainless lines on all four corners makes a huge differece in pedal feel.
you'd be surprised how many track whores run the plain stock $70 oem brembo rotors.
the eradispeeds do not clear the 00R brembos, should you ever wish to step up (price is coming down on those 00r m-2300-x kits too - under $900 at most places now)
i run a two piece rotor that i assembled myself. when i order the rotor disc itself, i get it balanced and stress relieved. might try cryo treated next time, for longer life.
gas slots give my steering wheel a little nibble. i can definately feel them through both the pedal and the steering wheel.
