crfine88's Z4M Track Machine

If you want to see how to properly modify a BMW for the racetrack, then look no further than crfine88's Z4M. This coupe has been built with only the racetrack in mind: modifications such as a weld-in roll cage, a supercharger kit, some lightweight wheels, a big brake kit, a carbon fiber driver's seat, passenger seat delete, an extended shift knob, a racing steering wheel, a lightweight battery, full exhaust, custom carbon lip and carbon fiber rear wing all attest to this. Not only has every single modification been meticulously thought-out, planned and tested, this owner also goes through great lengths to keep his car looking super clean. Enjoy!
