I've heard of some cheaper aftermarket drilled or slotted rotors cracking. My vote is still on the GT oem rotor upgrade. The difference may not be massive, but for $225 you won't at all feel like you threw away your money.
Alright, I'm gonna go with the set up that you have
so what all I need is the GT oem rotors and calipers with a good set of pads
call you all tell me what are some really good pads
thanks for the advice!
