OS Giken Mini R56 Cooper S STR Twin Plate Clutch overhaul kit B (STR2C) All components are chemically heatThe STR Clutch line up was designed to hold high capacity power while still retaining a relatively light clutch pedal. This technology was driven from our racer's demand for a lighter clutch during long endurance races in Japan. Heavy clutch pedals lead to driver fatigue during long endurance racing.
