This kit includes sprung centre cushioned button type discs that offer a level of performance above organic discs, while requiring little compromise in driving style and vehicle usage. Mantic 9000 series clutches are twin disc, 9” (225mm) diameter modular clutches that are designed for high performance cars. Mantic 9000 series are low MOI (Moment of Inertia) clutches that offer a level of performance not only superior to a single disc unit, but also allow you to select options that best suit you. All 9000 series clutches are made with premium quality materials designed to perform and last the distance. These kits offer up to 1010ft lbs (1365Nm) of torque drive capability. The key to the 9000 series is the street drivability of the Sprung Street Cerametallic discs. These suit high performance engines and enthusiastic driving styles, while allowing excellent drivability when needed. Low pedal effort is another bonus.
