The BMW M4 exterior carbon package comes as a standard feature. It has 20-inch wheels, which is a great addition for those who want to increase the car’s looks. The pack adds a carbon fibre rear diffuser and front air intake inlays. The M4 also features a special illuminated M badge, which can be found on the roof. The seats are made from carbon fiber and weigh around 21 pounds less than the standard M4’s. The interior includes piano black and carbon fiber trim, which make the M4 look even more luxurious.
