Description Reviews MINI Cooper Rear Rotors! Here is a set of basic plain faced rotors that work like stock but without the cost. They come finish ground after they put a high quality coat of black paint on it to combat rust when on the vehicle. They then cover them with a oil coat then put into a bag to combat rust during self life. When installing these rotors, you want to wash them down good with brake clean to get off all the oil before using them. We use these rotors a lot here at the shop and recommend them! Note: Sold as a pair of two.
