It's a 3 puck on one side and solid on the other. It's got about 25,000 miles on it and many drag strip launches and it still looks great. When I put the motor back in with the sport 600's two weeks ago I figured what the hell and put the same old clutch back in and try to kill it. The Pressure plate & flywheel were in excellent shape. And wouldn't you know, it holds perfect. I punched it at 60 in 3rd a bunch of times and the tires just bust loose and I see the speedo go right to 80mph. It holds 4th perfect too. I put it in as a replacement disc in my centerforce DF pressure plate after it's origional disc was toast. Whatever clutch I get when this one finally dies will be another kind of carbon fiber clutch that's for sure.
