Most people think installing mudflaps on a front wheel drive car doesn’t make sense. However, the Fiesta ST is one of the few exceptions to this. The ST utilizes a somewhat fake torque vectoring system. Rather than limiting the torque through differentials or engine power the ST cuts power to specific wheels by utilizing the brakes. This can cause the brakes and gas to be engaged at the same time and causes significant brake dust to build up along the side of the car. In addition to this the Fiesta ST can very easily brake the wheels loose and since it is front wheel drive the rocks and dirt that gets kicked up ends up hitting the side of the car as well.
