OS Giken STR Series twin-plate clutch with a soft diaphragm for Mitsubishi Lancer Evolution 1–3 (CE9A). The STR twin-plate uses a soft diaphragm design to moderate pedal feel while delivering additional clamp capacity from two friction surfaces. Intended as an upgraded direct-replacement, it gives early Evo CE9A cars more holding power with attention to smoother engagement and reduced driveline shock.
