Its safe to say that BMWs new take on the front grille for the 4 Series, M3, and M4 has rapidly split its fan base in two camps. Even we raised a lot of eyebrows while looking at the press photos but a recent first contact review with the 4 Series taught us that the loathed grille looks a lot better in the metal. Still, this aspect hasnt stopped Prior Design from developing a fix for those wanting a more traditional grille approach on their M4.
