VTT is proud to offer the only complete S55 / N55 complete crank hub solution that does NOT require the crank to be drilled for pins. Checkout some of the results from 2x different F80 M3's that StudioRSR repaired. The notorious 'spun crank hub' has become a fairly common repair for the S55 engine and is now a prevalent preventative maintenance item for F80 M3 / F82 M4 owners to prevent a potentially catastrophic failure from occurring.
