S.P.E.C., Inc Clutches and Flywheels introduces a line of configurable multidisc clutch and flywheel assemblies for the Mitsubishi EVO VIII and IX 4G63 engine.   These units are purpose built for each of 4 different types of driving: street, road race, drag and drift.  Each carries a different inertia requirement, as well as different load and friction properties.  SPEC manufactures to an industry leading one thousandth of an inch for perfect rotational properties and concentric actuation, which optimizes balance, drivability and life.

Each kit includes a CNC billet hydraulic throwout bearing, high strength racing bolt kit, and SFI certification.  SFI rating is a safety process by which all SPEC multidisc clutches and flywheels are certified and guaranteed.   Each component is bolt-in replaceable, so the assemblies are rebuildable by the end user.  Replacement components and rebuild services are always available.
