CDC - re focus engine vibration?

I have never had any dealings with Sachs kits but being German would expect good quality from them.have fitted after market clutch/DMF kits to some motors and have experienced poor quality/problems,ie.g/box out again after 2k miles.There are instances where solid flywheel/clutch kits are available now but personally would fit like for like where possible.DMF`s are there for a reason and think you are doing the correct thing fitting one.
