ARP Harmonic Damper Bolt Set, BMW S58 Coupe - Lowers Intake Air TempsBMW OEM damper bolts are grade 10 and Torque to Yield, designed for one time use. While this is adequate for factory power levels, these bolts fall short when power levels are increased. 5150 AutoSport has observed damper bolts coming loose and breaking, leading to engine and crank damage, as well as improper torque load between bolts. The factory bolts are simply not sufficient for those planning to run above factory power levels. 5150 AutoSport
