OS Giken R2C Twin Plate Clutch Kit For Mitsubishi Legnum VR4 6A13Includes required movement alteration kit for OS Giken clutch installation. The R2C twin plate clutch is recommended for racing use and cars with high horsepower (up to 700ps). It uses a single hub to reduce input shaft wear, which is splined onto the two friction discs. It has no damping springs for minimum weight and most positive engagement. This also reduces the cost of rebuilding the clutch.
