The 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. Available in single and twin plate configurations matched with a unique clutch cover which allows for factory like clutch pedal feel.
