Hi I have a taxi repair garage in Perth and fit flywheel conversions all the time.
Last year we did over 30 conversions on skoda octavia cars and have no problems what so ever on cars doing 2000 miles a week on average.
Dualmass flywheels are a fairly recent add on to cars before them we only had solid flywheels. In 30 odd years of the motor trade I have only replace a handfull of solid ones but hundreds of dualmass types.
The solid flywheel clutches contain thrust springs to obsorb sudden torque where dualmass clutches have no thrust springs and require the dualmass to obsorb the torque so in short solid flywheel clutches do the same job better and more reliable as well as being far cheaper.
The octavia flywheel conversion is very easy to do and should be completed in under three hours.
