ahhhhm ... no mate ... warped rotors can be machine straight again, no need to throw them away if they are still well within minimum size limits. and as for new brake pads, again u can reuse them if there is still plenty of meat on them, they just need to be rubbed back to remove grooves and uneven wear. as for slottered and cross drilled rotors, they can be machined just like normal rotors
