It's a controversial change. The DMF attentuates torsional vibration. If you replace it with a solid one, the vibration will be transmitted somewhere else where it can cause damage.

DMF were notorious for premature failure and became unpopular. Some people say that manufacturers simply stopped using DMF and went back to solid flywheels. This isn't true. As fuel injection systems were improved, the engine vibration could be reduced at the point of source-thereby rendering the DMF redundant. That's not the same thing as bolting a solid flywheel onto an engine that suffers from heavy vibration.

That said a lot of people have converted and swear by the change.
