      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. 

      The STR2C Twin plate dampened clutches give some forgiveness to the transmission by absorbing drivetrain shock while providing reliability and strength under heavy abuse. The end result is a quiet and reliable clutch set that will go years before needing overhaul. The STR2C is good up to about 575 lbs ft torque maximum.
