Has anyone replaced their dual-mass flywheel with a single-mass? Did you notice much difference?
My dad was an automotive engineer for AP and spent years working on what were then called twin-mass flywheels. They were developed and fitted by car manufacturers to reduce noise, vibration and harshness (NVH), so I'd presume that replacing one with a single mass flywheel would result in an increase in NVH.
If it ever comes up in conversation, ask if they did a comparison of the dual clutch plate fitted to the alfa gtv. Also if the dual mass needs a different driving style less to no engine braking but more using the brakes.
