Have a spec twin disk that has seen 4-5k miles of use. No strip, just street with an occasional pull here and there. Appears to be in good condition, pads still look to be in great shape with lots of life left, tried showing as much as I could in the pics but if you want any other pictures let me know. Clutch disks are sprung to absorb some impact from shifting gears and should be easier on the transmission than a MCLEOD RXT or other non sprung clutch. Spec claims it can hold up to around 1000 lbs/ft of torque, I have half that so I can't say for certain other then it never slipped on me. If your in central Ohio you can come by and check it out in person. Price is 650 shipped to your door. If it's still posted it's still available. If you have any questions let me know.
