I use StopTech's Power Slot rotors and Street Performance Pads.
I've had really consistent performance on track, and have used them for the past 4-5 years. They're a lot lower dusting then the OEM pads, but I guess almost any alternative would be compared to OEM hehe. Good fit, no rattles or squeaks.
The best part is the price. If you purchase from Amazon, set of pads are only $104 (fronts $58, rears $45), and rotors are $80-90. So full set for $500 (vs $700+ when I used to purchase from the vendors here).
Super great value for performance if cost is a major factor.
