M2C / M3 F80 / M4 F8x S55 and 35i F-Series N55 MMX Crank Hub Capture Plate

Specially designed for the BMW S55 engines found in the M2 Competition / M3 F80 / M4 F8x and the N55 engines found in the M2 F87 / 135i / 235i / 335i or 435i F-Series, this MMX crank hub capture plate secures the original centre bolt to help reduce the risk of loosening caused by engine vibrations and harmonics. By physically preventing the bolt from rotating, this machined 6061 aluminium component provides a useful preventive upgrade, especially on tuned engines.
