Some people think that the drilled rotors can tend to warp more easily than the normal ones... I think slotted is a good compromise from what I've read. I will be getting some ATE slotted rotors next time mine need replacing but haven't had any problems with the standard ones so far.Originally Posted by vping
I will always change discs and pads together, but I know a lot of people who have changed one or the other and not had problems. If the pad hasn't worn evenly on the old disc then it will have a negative effect on the new one... Personally, I'd do both.
