Reply to "Dual Disc clutch"

davidnunnMember

Power handling isn't the only reason to use a dual disc clutch. The BMW M1 used a dual disc clutch with a ZF transaxle. They did it in order to make the bell housing as small as possible, so they could mount the drivetrain as low as possible but still have reasonable clamping force and good ground clearance. I believe the discs were about 8" in diameter. Using a small diameter flywheel and clutch also reduces the moment of inertia, so the engine will rev more easily.
