the BMW S55 engine found in the M2 comp M3 and M3 vehicles, tend to suffer from a failure with the crank hub spinning, this tends to happen when running additional torque caused by increasing the vehicle power output.
This additional torque causing the crank to spin causing the engine to lose its timing and can result in a catastrophic engine failure.
Litchfield Motors have engineered a capture plate to help stop the crank hub spinning. This is something you can replace as a preventative measure or if the vehicle is running a stage 1 remap. If you are planning on running stage 2 or higher Litchfield also offer a full replacement crank hub.
