As far from JBS as possible !
A Duel Mass Flywheel ( DMF ) has springs in the center of two plates which let the DMF take up the vibration from the gear linkage. If you fit a Single Mass Flywheel ( SMF ) you will notice a very loud rattle when in neutral plus reversing and when driving slowly with low revs. Unless you intend to tune your car to over 380+ lb torque i wouldn`t even think about it. My car was running 440lb torque for nearly two years with a DMF and the only reason i fitted a SMF was that no company makes a clutch for my car to hold 600 lb torque with a DMF as the would probably soon kill itself at that power.
