Quarter Master Optimum-SR For LS Engines
Optimum-SR™ 10.4" Two-Disc LS Clutches. They have achieved standout results with a Camaro in the GRAND-AM Continental Tire Sports Car Challenge Series, including a first and second-place sweep at the Indianapolis Motor Speedway. Now, with lessons learned from racing, and with the data from extensive drivability testing, Optimum-SR™ LS Clutches are available for street use. Features a spring designed to require only a 10 percent increase in pedal effort over stock, with stock-type modulation control. The clutches are capable of handling 1400 horsepower and 1000 ft.-lbs. of torque. Features a sprung hub, marcel-type discs with organic rag-type friction for smooth engagement. A vented floater plate and grooved friction surfaces provide better cooling as well. Featuring aircraft-grade bolts and hardware with an all-billet construction, each clutch is completely rebuildable and can be used with OE hydraulic bearing systems or Quarter Master® Tri-Lite II Hydraulic Release Bearings.
