R56 Crank Bolt Lockdown Plate

With the design of the crank, pulley, and timing chain sprocket assembly in the MINI Cooper R56, there is the potential for catastrophic damage. If the bolt which secures the pulley hub and sprocket were to loosen over the life of the car, it would be possible for the timing chain sprocket to become misaligned on the crank. This could lead to damaged pistons, bent valves, or worse. The CravenSpeed Crank Bolt Lockdown Plate eliminates this possibility by making it physically impossible for the bolt to loosen itself.
