Quarter Master Industries Optimum-SR 10.4" Two-Disc LS Clutch
Optimum-SR 10.4" Clutch Kits are true racing components that feature factory driving characteristics -- allowing them to function as stock replacements.
Each 10.4" one- or two-disc clutch and flywheel kit incorporate engineering know-how derived from the rich Quarter Master® racing heritage. However, they can also easily be used for street driving. The two-disc kits are designed for up to 1400 horsepower and 1000 ft./lbs. of torque. The single-disc options can hold up to 700 horsepower and 500 ft./lbs. of torque.
Quarter Master®, the industry leader in driveline technology, has continued its winning ways with 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.

Has anyone tried one of these yet? Very interesting design with the vented floater disc. The ability to rebuild is always a plus.
It says that the clutch discs are organic. Can you elaborate more on the clutch disc material. Also what is the price to rebuild one of these assemblies?

We current run this clutch in our road race 625hp race car. The clutch has been in the car 3 years we finally rebuilt it this year after 3 seasons of track and race events we only replaced the hardware and friction disc which ran about $775.00 the cost of rebuld would of coarse be predicated on what needs replacing.
Organic refers to the materials that the clutch disc is made from; that is metal fibre interwoven with organic materials.
Organic clutches are suited to a range of driving conditions, and perform well in city traffic.

Like you I have noticed these for some time, but never really see people running them. I like the vented floater plate, grooved surfaces, and sprung hubs. I wonder if they would ever change the material of the clutch lining to something more of a street/drag material. I believe retail is int he $2500 range though.

Looks like a great design. Would they be interested in offering it with more aggressive disks that are non-organic and increase the rating to at least 1200 ft-lbs?
