The Mantic Advantage

Our Mantic Clutch kit uses the unique sprung center with cushioned twin disc design. This equates to more torque capacity and heat resistance while retaining excellent drivability. The Mantic twin disc clutches also use 9" diameter discs that greatly reduces the MOI (Moment of Inertia). This allows more power to the ground as well as quicker more precise shifts. The lightweight flywheel revs quicker compared to the heavier OE flywheels. The billet red cover and supporting components are machined from billet stock adding strength and durability. Billet will not flex under heavy load like the typical weaker stamped steel kits.
