I've got an 89 celica GT and I've been thinking about buying drilled or slotted rotors, but I've heard they brake down quicker and are much worse than stock rotors. Is it true, or are they worth the extra money? Also, what pads are the best for them? In fact, what pads are best for even regular rotors to decrease the amount of brake dust. Please help me because I need to change those brakes quick. Thanks everybody!!
