Over 60k miles ago I got a pair of brembo brakes, the rotors are worn out and the pads are gone. These rotors are dual disk and some of the hardware is stripped. My question is, can I still use the stock rotor or will I have to buy another set of brembo rotes and pads. (Brembo only came with front brakes for is300) rear brakes remain stock but have the drilled and slotted twin plate.
