Concerned that your BMW M4 is not aggressive or noticeable enough? Next time, order it from the factory slathered in Sakhir Orange, a color that resembles liquid fire, and then send it to Dinan—a BMW sanctioned aftermarket tuner based in CA—for the $8,755 exterior upgrade package, which includes the meanest set of black matte, 20” forged wheels bursting with Pirelli P-Zero Corsa tires ever ram-jammed into the wheel wells a small-ish sport coupe. With 305 mm rubber in the rear, it looks like the M4 mounted and devoured a Countach. Or a Caterpillar earthmover.
