As aggressive and fresh as the M4 looks from the factory, there is always room for improvement with any car. M Performance parts tend to be the go to parts when it comes to modifying the exterior of the F8X M3/M4. Made by BMW themselves, all of the parts are not only a guaranteed fit, but hold a high level of quality and give a top notch appearance to the car. For some, adding the carbon fiber M Performance splitters and the M Performance front lip make the front bumper the perfect height from the ground, while being on the stock M suspension. If adding the splitters, the mirror caps can’t be forgotten, adding an equally elegant and strong finish to this Mineral White Metallic M4's exterior.
