Just to update people on this item. Although BMW say mudflaps are not suitable for 330I M Sports I can now tell you that they fit perfectly. Took a chance and purchased the 3 series BMW mudflaps. (Front 82 16 2 218 983) (Rear 82 16 2 218 984) Fitting was straightforward. Installation Instructions are on the internet (Mud Flaps Retrofit Kit BMW 3 Series (F30,F31). Front is easiest as you can put steering on full lock to get at your job. Rear is a bit harder because of restricted space between wheel and wing. Some say you need to remove the rear wheels. I managed it without removing the wheels using 8mm socket, short bar and racket. A little fiddly but possible with patience. Black mudflaps on a black car look fine although my reason for adding them is to do with preventing the mud, horse and cow muck from the car sides as I often travel on some roads used by farm vehicles and animals. Both sets cost £80 when purchsed via the internet. Rob,
