My experience with pucks is not the same as others. I dont like them, i like organic plates. Mine slipped and when i replaced the 6 puk with a organic plate, it held. May have been the puks were too thin, or too many pucks, i dunno.
The fact about pucks is that the pucks are harder than the flywheel and the pressure plate. So the friction surface becomes those parts, the buttons dont hardly wear. If you try to ride a puck, it will chew out your flywheel and pressure plate fairly quick. Dont ride them.
