Part of the Transmission and drivetrain guides.
The disc, cover and flywheel work as one assembly. These guides cover friction materials and button construction, clamp load and cover design, flywheel resurfacing, and when a dual-mass flywheel should be converted — with the fitment details that decide whether the assembly will hold torque and stay quiet.

Frequently asked questions
Does a new clutch disc need a resurfaced flywheel?
In most cases yes. A worn flywheel surface prevents the new disc from bedding in, causes judder and shortens clutch life. Check runout and surface condition, and follow the manufacturer’s minimum thickness before deciding.
Should I convert a dual-mass flywheel to a single-mass unit?
Only with a clear reason. A single-mass conversion is cheaper and more robust for some performance and commercial uses, but it can introduce gearbox rattle and harsher engagement. Match the decision to the duty cycle.
