OS Giken Mitsubishi CP9A Lancer Evo 4-9 STR Twin Plate clutch kit (STR2C) These tools imitate the transmissionThe 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. The STR2C Twin plate feature solid hub clutch disks to provide efficient transfer of power while providing reliability and strength under heavy abuse.
