BR Motorsport 3 Pin Crank Hub

A common issue with the S55 is crank hub failure/slip due to the OE design of using a central bolt & friction washers to keep the engine in time. Both when tuned and stock usually during downchanges due to the torque load against the crankshaft, the OE hub can slip and cause timing misalignment which can result in engine limp mode/lack of power and or bent inlet/exhaust valves as worst case scenario.
