Terminology review:

A "rag" clutch. Basic and typical clutch composition on both sides covering the entire surface of the disc. Typical of a clutch you might buy from NAPA or where ever.

A "puck" style clutch. Little "pucks", spaced apart, not fully covering the entire surface of the disc. Composition varies, size varies. Typically obtained from a more serious "race type" outlet.

Or a combination, rag on one side, puck on the other.
