These Mirror Base Plates will work with all of our M3, DTM, Z2 & F1 style mirrors. They allow the direct fitment of these mirrors to a wide range of cars. These base plates fit in-between the mirrors and the car and act like adaptors to give a snug fit. The amount of work involved in fitting mirrors & base plates will vary from car to car. Even when using an appropriate base plate you may find that a little modification work is necessary for a good fit. For this reason we recommend that fitting should only be tackled by a competent person.
