I definitely agree with everything mentioned above. I made the mistake of getting the cross drilled rotors from R1 concepts and while they were great initially, I warped them fairly quickly and they squeal like crazy unless you're doing super hard braking. For daily duty, they are overkill and will be very noisy. However, I did do the stainless lines and that made a HUGE difference. The pedal feel is night and day better. Bang for your buck, do the stainless line upgrade, better pad and either keep the OEM rotors or go with R1 slotted, but again stay away from cross drilled... just my .02.
Quick addition, I switched back to OEM rotors and kept my braided lines and still have great pedal feel without the squeal.
