The S55 engine is a highly capable motor in the newer M3 and M4. Being taken to the track fairly often, the owner of this Mineral White F82 was seeking more performance to decrease lap times. When preparing a car for the track, safety should come before anything. In the event of an accident the driver must be in as good preparation as possible.
