Yeah it would be silly to change just one piece given how long it takes to get at it all. It would be the labour cost all over again!

The dmf removes vibration and smooths out the engine. I have heard horror stories about smf destroying gearbox due to the vibrations transmitted to them and things, don't know anyone who has done it though.


Before the advent of DMFs the clutch driven plates were fitted with springs to absorb these vibrations. I guess the DMF was found to do a more effective job. I wonder if the SMF conversions include a spring-damped clutch plate.
