This is a full-face clutch, meaning there's friction material on the entire surface. Race clutches are described as being four-, six-, or eight-puck designs; these look like fan blades. The friction material on these race-only clutches is more substantial so less can be used, which lightens the clutch to speed the engagement process. The tradeoff is harsh engagement and chattering. A clutch's friction material and its disc configuration are where many compromises unfold.
