The advantage of the multidisc setup comes from being able to use a smaller diameter disc, which is easier to engage, without loosing contact surface area. You can increase the diameter of a single disc, or switch to a multidisc setup.

Multidisc To up the friction material's surface area, you can do one of two things. This is the only thing a manufacturer or rebuilder can do to the clutch disc to relieve chatter without changing the composition of the friction material. A Marcel is a crimped plate between the two layers of friction material that acts as a spring to cushion the engagement and disengagement of the clutch. The way the top clutch manufacturers combat this problem is to employ what is called the Marcel. The nature of the harder, longer lasting, grippier materials that are best at managing high torque loads is that they are more prone to chatter. The best thing to do first is to fix all the non-clutch variables. Worn U-joints, incorrect pinion angle, a bad finish on the flywheel or pressure plate, loose motor mounts, a worn pilot bushing, or any loose drivetrain or suspension components can exacerbate what may have started out as a chatter too minor to have noticed on its own. The clutch is not the only thing responsible for this feeling, though it is a major contributor. Chatter Chatter occurs when two hard surfaces touch each other, and a vibration is started.
