If dampening springs are weak, you can expect limited pin contact and clutch chatter. Another clutch disc dynamic is called Marcel, or "Marceling," which is the amount of disc compression that ...

F.Virtually all street clutches also employ what is called a Marcel spring between the two facings of the clutch friction material. This is a very thin, wavy spring that also helps to damp the ...

While this is a great way to reduce inertia, it comes at a price for streetability: no "marcel" spring. On full-circle clutch discs, the friction material is typically attached to a carrier that ...

Friction lag is influenced by spring rates. In the clutch disc department, suppose we categorize the types as having (1) unbacked facing with marcel cushioning, (2) backed facing with and without ...
